Every Level, One Set
PowerFlex gives you five resistance bands so your workout grows with your strength. Vellhaven built it to replace a whole rack of gym equipment.
Built To Take The Stretch
Reinforced latex holds its shape through thousands of reps. These bands are made to stretch hard and keep coming back for more.
Your Gym, Wherever You Are
Fold them into a bag and train at home, at the park, or on the road. Vellhaven made strength training genuinely portable.

Frequently Asked Questions
What resistance levels are included?
The set includes five bands ranging from light to heavy, so you can match resistance to any exercise or fitness level.
Are they suitable for beginners?
Absolutely. Start with the lighter bands and work up as you get stronger, using the same set the whole way.
What are the bands made of?
PowerFlex bands use durable natural latex, chosen for its stretch and its ability to bounce back rep after rep.
Can I use them for physical therapy?
Yes, the lighter bands are gentle enough for rehab style stretching and mobility work, while the heavier ones handle strength training.
How do I care for the bands?
Wipe them down after use and store them away from direct sunlight to keep the latex flexible for years of workouts.
