Did you know?

Unlike dumbbells, elastic bands give you variable, gradual resistance. This lets you work on your strength, speed and power while reducing the stress you place on your joints.

HOW TO USE YOUR PRODUCT

The expander is adjustable as you progress: You can choose the resistance to suit your level or the exercise.
If you are a beginner, the 5 elastics may be too difficult to pull to complete the movement perfectly. Start with 1 or 2 bands, then increase gradually.
