Athlete of the month April: William Mooijman

William Mooijman has been named April’s athlete of the month. The 34-year-old William previously trained outside under the guidance of personal trainers Lorenzo and Kevin during the Corona period. He moved to Scheveningen last year. Since he lives opposite InTension, exercising at InTension was an easy choice for him. We see him at least 5 to 6 times a week. Boxing and strength training are his favorite sports days. Aside from his personal training sessions, William also attends instructor Luuk’s boxing class on Thursday evenings at 8 p.m. While William enjoys training alone, he prefers training with a buddy or in a group. Because of this, Nick and Luuk are currently leading a 12-week fitness program. By doing so, he is able to take his training to a higher level in a group setting, increasing strength, weight, and fitness. Fitness, health, and strength are important to William. As a result of the hard training at InTension and the social environment at the gym, he has energy for ten! Our congratulations go out to William on his selection as athlete of the month. For the entire month of April, his membership is on us!

Athlete of the month MARCH: Marleen Nauta

When Marleen Nauta moved to Scheveningen 7 years ago, she began looking for new gyms in the area. After wandering around for a while, she entered InTension and was instantly smitten! Along with the homely feeling, she appreciates the professional approach, involvement, and conviviality of InTension. She also participates in fun activities at the beach, workshops, and yoga weekends. At InTension, Marleen prefers the Power class (twice a week), Warm Yoga (twice a week), and Yin Yoga when she has time.

She used to focus solely on getting a ‘tight body’, but now that she also participates in the X-fittt program, under Stacey’s expert guidance, exercise is about much more: vitality. She defines it as a healthy relationship between mind, body, and soul. She exercises more, eats a healthy diet, quit smoking, and reduced her alcohol consumption to achieve this goal. As a result, she has become more relaxed, slept better, and her high blood pressure has decreased! She found everything she was looking for in a gym at InTension. Congratulations to Marleen on being named athlete of the month for March. It’s a free month for her in March!

This month’s tip: Feeling satisfied without overeating! Feeling fuller after eating

Is there anyone who doesn’t enjoy feeling satisfied after eating? By choosing the right foods, you can fill yourself up and boost your energy. Here are 8 tips to help you.

1. Eat Fiber-Rich Foods: High-fiber foods, such as whole grains, legumes, vegetables and fruits, take up more space in your stomach and keep you feeling full longer. As well as aiding digestion, they also promote a healthy weight.

2. Protein-rich foods: Protein-rich foods include lean meats, fish, eggs, dairy products, nuts, and seeds.

3. Consuming fat-rich foods, such as avocados, olive oil, nuts and oily fish, can help you feel full for longer periods of time. Additionally, they provide your body with essential nutrients.

4. Slow down and chew thoroughly when eating: By eating slowly and chewing thoroughly, your body can send the satiety signal to your brain. Overeating can be prevented by doing this.

5. Drink water: Sometimes thirst is mistaken for hunger. Try drinking a glass of water before eating to see if you’re just thirsty.

6. Consume foods with low energy density: Low energy density foods contain relatively few calories per gram. Many vegetables and fruits fall into this category.

7. Avoid overeating by serving smaller portions. Serve your meals on smaller plates and bowls, for example.

8. Prepare meals and snacks ahead of time: Planning your meals and snacks in advance can help you make healthy choices

Be careful not to overeat.

X-Fittt: lose weight with full reimbursement from your health insurance

X-Fittt at InTension has been in full swing since May. More than 50 people have signed up!

Combining sports with the nutrition app and coaching conversations with lifestyle coach Steffan is effective to help you improve your lifestyle. Every health insurance policy reimburses the guidance, which has been proven to be more effective than many other lifestyle programs.

A BMI above 28 (or 26 with complications such as diabetes, cardiovascular disease, etc.) is required for participation. Referrals from your GP can be used to schedule an intake. Referral letters are available at the entrance of InTension. Simply send an email to stefan@x-fittt.nl after completing the form. In addition to scheduling an intake, he provides further personal guidance.

For further questions, you can also email him or speak to him in the mornings on Monday, Tuesday, Wednesday, or Friday. Fill out the contact form to find out if the Xfittt lifestyle program is right for you. For more information, watch the video here.

Workshop Yin Yoga XL & Sound

Sunday afternoon, December 17 from 4:00 PM to 5:30 PM, our yoga instructor José will present a special workshop combining Yin Yoga & Sound. As you practice yin yoga postures, you will listen to your body as you connect them to sound. By making contact with your body on subtle layers, you can achieve total relaxation, softening, and transformation. In this workshop, you will learn what the vibration of sound can mean for your presence and awareness. In the busy month of December, a magical combination with Yin Yoga can help you regain balance. Take advantage of this wonderful afternoon as a gift to yourself this Christmas!
