Product Details:

1. These springs are only for chest expanders.

2. Use at least 3 springs on each end of the handles to avoid over-stretching. The warranty on the springs is 3 months, as they are considered a perishable item.

3. If the springs pull open easily, add one or more. You can remove or double up springs, adjusting the tension to suit your goals and experience level.

4. Pull and release slowly – the springs need cushioning when rebounding.
