FAQ
Do I need experience?
No. Our SilverFox classes are designed for adults aged 55+ of all fitness levels. Whether you're new to exercise, returning after a break or looking to stay active later in life, our experienced coaches will guide you every step of the way. Every class is adapted to your level, helping you build strength, improve balance and move with confidence.
​
Can beginners join?
Absolutely. Many of our SilverFox members had little or no previous training experience. Our coach-led small group classes provide personal guidance in a safe and welcoming environment, making it easy to build strength, improve mobility and stay active at your own pace.
​
How many classes should I take per week?
For most adults aged 55+, we recommend training two to three times per week. This allows your body enough time to recover while steadily improving strength, balance and overall fitness. If you're feeling great, you can always add an extra class. Our coaches are happy to help you find the right schedule for your goals.
​
How large are the groups?
Our SilverFox classes are intentionally kept small to provide plenty of personal attention. Most classes have 8 to 10 participants, with a maximum of 14 members. This allows our coaches to adapt exercises where needed and ensure everyone trains safely and confidently.
​
Can I combine different classes?
Yes. Many of our members combine SilverFox with our Strength classes or Personal Training. This combination helps improve strength, mobility, balance and overall fitness while supporting healthy ageing. Our coaches will gladly recommend the best combination based on your goals and experience.
​
Is there parking available?
Yes. Kracht Amsterdam is located in Amsterdam West (Houthavens) and offers free parking directly in front of the gym for members. This makes it easy to attend your SilverFox classes without worrying about parking.
​
What should I bring to my first class?
Simply wear comfortable sportswear, clean indoor training shoes and bring a water bottle. We'll take care of everything else. Your coach will welcome you, explain the exercises and make sure you feel comfortable from the very first class.
​
Do you offer a free trial?
Yes. We offer a free SilverFox trial class so you can experience our strength and mobility programme before becoming a member. Meet our experienced coaches, train in a welcoming small group and discover how regular exercise can help you stay active, healthy and independent.
​
What makes SilverFox different from other senior fitness programmes in Amsterdam?
SilverFox combines strength training, balance training and mobility in professionally coached small group classes designed specifically for adults aged 55+. Rather than simply exercising, you'll receive expert coaching focused on healthy ageing, fall prevention and maintaining an active, independent lifestyle in a supportive community.
Which programme is right for me?
That depends on your goals and current fitness level. Whether you're looking to improve strength, increase mobility, reduce the risk of falls or simply stay fit after 55, we'll help you choose the programme that suits you best. During your free trial, we'll recommend whether SilverFox, Strength classes or Personal Training is the right fit for you.
​
Why is strength training important after the age of 55?
Strength training is one of the most effective ways to stay healthy and independent as you get older. It helps maintain muscle mass, supports bone density, improves balance and mobility, and reduces the risk of falls. At SilverFox, our experienced coaches provide safe, progressive strength training specifically designed for adults aged 55+, helping you stay active and confident for years to come.
