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!

  • 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.
