Update group lessons

Dear members,

We are very happy that the government has decided that we can offer our group lessons again starting from thursday. We will return to our regular group lesson schedule (click here for our group lesson schedule) from two weeks ago. The KRAV MAGA lessons for adults will still be unavailable for the time being as we cannot stick to 1.5 meters distance there. The online classes we have been offering over the past two weeks can be viewed through the emails you received until December 3rd. If you want to join those, click on “Yes I want to participate”

We will still have to adhere to a number of strict measures to be able to continue to guarantee the safety of our members and our employees. Please read this again carefully:

  • Exercising is only allowed by “appointment”. You can make a reservation in advance through our online reservation system. Do you not yet have a username and password? Send an email to info@in-tension.nl and we will send you the necessary information for online reservations.
    This applies to our group lessons as well as independent training in our fitness area. You are allowed to train for a maximum of 1 hour and be present at InTension for a maximum of 5 minutes before starting. If you decide to come without reserving beforehand you risk not being able to work out due to the maximum capacity having been reached.
  • If you have to cancel your reservation make sure you do it on time (at least one hour in advance), so that those waiting on the reserve list don’t miss out.
  • Exercising is not allowed if you have a fever (38 degrees or higher), flu / cold and / or other Corona symptoms. In order to guarantee that our members don’t have a fever, the group lesson instructors will measure the temperature of all participants prior to the group lessons. At 38 degrees or higher, the person in question will unfortunately be sent home immediately. Members who are coming to exercise alone can measure their own temperature. Our Personal trainers and Physiotherapist will measure their own clients prior to the training.
  • We firmly request that you enter InTension already wearing your workout clothes. Participants for lessons in the InTensity area, main group lesson area and Spinning room can change shoes in that room and leave their other belongings there (clothing, bag, etc). The participants of the lessons in the Body & Mind area can place their shoes on the appropriate shoe racks and take their other belongings into the room. The participants for the HIT IT classes and those coming to exercise in the training area can change their shoes in the changing rooms and use the lockers to store other items.
  • Please do not use the changing rooms for changing your clothes, you are required to arrive and leave in your workout clothes.
  • Showers and saunas are still off limits.

We hope we have informed you sufficiently in this newsletter. We trust that you will respect our rules and regulations.

If you still have any questions after reading this news flash, feel free to send an email to info@in-tension.nl or contact our reception by phone at 070-3318811.

We look forward to seeing you in our group lessons!

Stay safe & stay strong!

Warm greetings,

Simon & Damaris

On behalf of everyone in the InTension team.

Workshop Restorative XL Yoga

This wonderful 2-hour Restorative Yoga workshop ensures that you fully recover from 2020 and start your 2021 with new energy! The workshop is less about “doing” and more about “being present”. We hold the sitting and lying postures for a longer period of time. That way we activate our so-called para-symphatic nervous system, the system that allows our body and brain to rest, recover and process. Body and mind are inseparably linked. Restorative yoga offers a wonderful opportunity to turn inward, peel off layers and surrender ourselves to who you really are inside. Restorative yoga poses are very comfortable and easy going and we aim to find a maximum relaxation. Perhaps this yoga form is not that much of a physical challenge, but all about letting go and surrendering yourself to calm and full presence, which may be much more challenging.

Treat yourself to the happiness of silence and tranquility in these hectic times. Are you up 13:30 to 15:30 on December 20th and will be hosted by our yoga instructor Jose. Fees are €20,- for members and €25,- for non-members.

Athlete of the month November

49-year-old Bianca has been a member of InTension since March of this year. She wanted to create a more active lifestyle for herself and so she joined InTension with all the best intentions right before the Corona crisis started. Shortly thereafter the lock down started… fortunately she had already gotten started in her workouts and followed the online lessons during that period. Now she is very grateful that we can stay open and enjoys at least five group lessons a week, including Spinning and Power. Since her start at InTension she has felt a lot fitter and her condition has improved considerably. As athlete of the month November, Bianca will receive her membership for free this month! We would like to wish Bianca lots of active fun and congratulate her on becoming Athlete of the Month!

Yoga Workshop Parents & Toddlers 2-4 years

On Sunday October 18th from 14:00 to 15:30 our yoga instructors Rachel and Fi will host a Yoga Workshop for Parents & Toddlers ages 2-4! In this workshop the connection between parent and child plays a central part. In a playful way you will be guided through the world of Yoga with your child. Your toddler’s motor skills and imagination will be stimulated but you will also work together with your child on various breathing exercises. We will also pay attention to yoga “games” that are highly educational and can be applied in daily life situations with your toddler. Would you and your child like to discover what yoga can do for you both? Then sign up for this special workshop at InTension! Send an email to info@in-tension.nl to sign up. Please state your name and the name of your child in the email. Fees for the workshop for you and your child are 20 euros for members and 25 euros for non-members.

We’re back with HIT IT

HIT IT is a challenging “small group” lesson combining functional strength exercises and high intensity cardio training. Each participant wears a Polar heart rate monitor so that the heart rates can be followed on a large communal screen. The trainer coaches all participants to the correct heart rate zone to achieve the optimal “HIT” effect. This zone is called the “orange zone”, in which the body creates an EPOC effect. As a result, you will not only burn calories during this training, but also a lot after the training! Who’s up for the challenge? HIT IT! See our AUTUMN group lesson schedule for the current lesson times. You can reserve through flow.polar.com. If you don’t have your own account yet:

–       Go to the website flow.polar.com
–       Create a ‘new account’
–       Log in with your new log in details
–       Click on ‘Community’ on the menu at the top of the page
–       Click on ‘Clubs’ in the second menu from the top
–       Look for ‘Intension’
–       Click on the InTension logo
–       Reserve the class you want

Aerosols don’t stand a chance

InTension Health Club is the first gym in Scheveningen where dangerous aerosols no longer stand a chance!

In addition to adhering to the existing RIVM rules and regulations (including the 1.5 meter distance rule), InTension Health Club is extremely well ventilated. Our current High Tech climate system ensures that fresh air is blown in from outside and the air inside is blown back out.

Despite all of the safety measures already in place we are taking things one step further by purchasing new air purifiers. With these new purifiers the air quality will be optimized in all our rooms so that dangerous aerosols no longer stand a chance.

Scientific research has shown the following results:



This way we can create an extremely safe environment for both our members and our employees.

Improve your immune system in this healthy environment! Stay safe & strong!

We’ve got good news!

Despite not being able to physically open our doors yet, we have been working hard over the past two months to provide our members with alternative options in order to keep moving and stay fit. We have adapted and added various activities:

  • our WODs (workout of the day) on Facebook
  • the online lessons on Fitsnacks.tv
  • the live online classes hosted by our own instructors (Yoga, Yin Yoga, X-Core, Power, Fitness & Total Body)
  • Outdoor Fitness Circuit on the square behind InTension
  • Outdoor Youth Fitness and 55 Fit on the square behind InTension
  • Body & Mind classes in the Westbroekpark and on the beach at Boonoonoonoos
  • Every Sunday a SPECIAL workout on the beach at Boonoonoonoos (Bootcamp, Aerobics and X-Core)

Starting this week we will also start offering our unique outdoor “Silent Spinning” classes on the square behind InTension. Every participant will receive a headset on one of our spinning bikes and will hear the instructor’s music and instructions. Would you like to join? These are the lesson times:

  • Mondays, Wednesdays, Fridays, Saturdays & Sundays at 09:30 & 10:00
  • Mondays & Thursdays at 18:30 & 19:00
  • Wednesdays at 18:00, 18:30 & 19:00

These 30 minute classes can be combined with our outdoor fitness classes that are adjacent to this.

We hope to receive more clarity from the government soon about a possible earlier opening date. If we are not allowed to open our doors yet on June 1st you will be able to continue choosing one the three options we provided you the last time. These options allow you to choose how you want to continue supporting InTension. We will of course respect any choice you make:

Option 1: I am a supporter of InTension Health Club and will continue to pay my membership fees. I feel it’s important to continue supporting my club in these difficult times.

Option 2: I am a supporter of InTension Health Club but please debit 50% of my membership fees for the time that InTension is closed.

Option 3: I am a supporter of InTension Health Club but I’m struggling as it is, so I would like to freeze my membership for the time that InTension is closed.

Please note that when choosing option 3 (freeze) you cannot make use of any of the lessons during the time that InTension is closed.

If you don’t inform us of any changes we will assume that your choice regarding your membership is the same as the one that you made for the month of May. If you prefer to choose another option you can send an email to info@in-tension.nl. Have fun with all of the other activities for now!

Stay strong & safe!

InTension is going outside

Good news! InTension is going outside! Although we are not allowed to open the physical doors to the gym for the time being, starting on Monday, May 11th we will add outdoor lessons to our program as well as continue our online live lessons. These outdoor lessons will be led by our trusted instructors at three different locations near InTension. This will be done within the frameworks that the government has drawn up on the basis of the RIVM guidelines. This way, InTension is a little step closer to its members! 

Click here to check out our lesson schedule


Starting on Monday May 11th, we will offer outdoor Fitness classes and various outdoor Body & Mind classes at three different locations near InTension: on the big square out in front of InTension, in the Westbroekpark and at Beachclub Boonoonoonoos. This is the schedule for our outdoor lessons: nog toevoegen

Participation in our outdoor lessons is only possible by appointment through our online reservation system on our website www.in-tension.nl. Do you not yet have login details? Send an email to info@in-tension.nlIf the morning outdoor lessons cannot take place due to the weather conditions, the instructor will notify everyone on Facebook around 8 a.m. and around 5 p.m. regarding the evening outdoor lessons. So follow our Facebook page at https://www.facebook.com/intensionhealthclub/ to check whether or not the lesson will go ahead that morning or evening.

It is important that you stay at home in case of any health complaints like a fever, flu, cold and / or other Corona-related symptoms. We kindly request you avoid physical contact with the instructor and other participants and keep a distance of at least 1.5 meters. Bringing your own towel and water is mandatory. There is no changing room and toilet visits are unfortunately not possible.

  • Outdoor Fitness: in the square

On the big square in front of InTension we will host 6 outdoor Fitness classes in the mornings from Monday to Sunday from 9 am to noon and 6 outdoor Fitness classes in the evenings from Monday to Thursday from 6 pm to 9 pm. This outdoor Fitness class is a 30-minute intensive Total Body workout based on functional exercises. It’s similar to our InTensity lesson. The classes are open to everyone since every participant can train at his or her own level. For our 55+ group, we’ll organize a custom 55+ outdoor Fitness class on Tuesdays and Thursdays in the last half hour from 11:00 am to 11:45 am.

We use the ‘come & go’ system in the flow of these lessons: make sure you are present on the square just before the start of the lesson and leave the square immediately after cleaning the materials so that the next group can start right away.

  • Outdoor Youth Fitness: in the square

We will also offer a Youth Fitness class on the big square in front of InTension 3 times a week on Monday and Friday from 17:15 – 18:00 pm and wednesday from 16:00 – 16:45 pm.

  • Outdoor Body & Mind classes: at the park / on the beach

Our outdoor Body & Mind classes “at the park” will take place during the week in the Westbroekpark. We’ll meet at the bridge at the entrance of the Westbroekpark on the side of Korfbalvereniging KVS. Five minutes before the start of the lesson the group will enter the park together and search for a quiet and suitable place together with the instructor.

The outdoor Yoga class “on the beach” is on Saturday morning and takes place on the beach at Beachclub Boonoonoonoos. We’ll meet on the stairs in front of Boonoonoonoos. The instructor will take the group to where the lesson will take place five minutes before the start.

You are required to bring your own yoga mat to participate in our outdoor Body & Mind classes.

  • Outdoor SPECIALS: on the beach

On Sundays in May we will have three outdoor SPECIALS at 11 am:

May 31st X-Core by Lorenzo

We’ll meet on the stairs in front of Boonoonoonoos. The instructor will take the group to where the lesson will take place five minutes before the start of the lesson. We will provide the X-Core tubes for the lesson of May 31st. If you have your own X-Core tube then please bring that instead.


Considering the outdoor lessons actually taking place is dependent on the weather conditions we will continue to offer the various online live lessons we have so far over the coming period. Are you not receiving the daily invitations to the online lessons and would you like to? Send an email to info@in-tension.nl.

You can also view all our online lessons  that we offer from now on. To do this click on “Yes, I want to participate” in the invitation email of the lesson you want to join and you can view it again.


As a result of our compensation proposal (see https://www.in-tension.nl/nieuws/voorstel-compensatie/), if you opted for option 3 (to pause your membership for the time being) then unfortunately you cannot participate in our outdoor lessons and online live lesson. If you would like to participate in these lessons you are free to go back to option 1 (continue to pay in full) or option 2 (50% discount). You can let us know by sending an email to info@in-tension.nl.

We are so happy that we will see some of you starting next Monday, out in the open air!
