The angle of your body is what controls difficulty in suspension work, not the equipment itself. A strap that holds its adjustment properly lets you trust that angle every single rep.
About the AnchorFlex Suspension Trainer
The AnchorFlex Suspension Trainer is a single anchored system that turns your own bodyweight into the only resistance you need. The straps are woven from cotton webbing, chosen for its grip against stainless steel buckle hardware, which means the length adjustment holds firm mid-exercise instead of creeping as you move. The foam handles are shaped from high-density foam dense enough to resist compression over long sets, so your grip stays steady through rows, presses and planks alike. It sets up on a single anchor point, whether that is a door frame with the included anchor or any fixed overhead point strong enough to hold your weight. Once anchored, the two independent straps let you angle your body for dozens of variations, from a shallow lean for beginners to a steep angle for a harder pull. When the session is done, it folds down into its cotton carry bag small enough to keep in a drawer or take on the road.

Frequently asked questions
What can I anchor the trainer to? +
Use the included door anchor on a closed door frame, or attach directly to any fixed overhead point rated to hold your bodyweight, such as a sturdy beam.
Will the straps slip once adjusted? +
No, the stainless steel buckles are designed to grip the cotton webbing firmly once set, holding the length through the full movement.
Is it suitable for beginners? +
Yes, a shallow body angle makes most exercises easier, so you can start gentle and increase the angle as you get more comfortable with the movements.
How do I clean the straps? +
Wipe the cotton webbing with a damp cloth and let it air dry fully before folding it back into the carry bag.
