Typically, a person is stronger at certain point of a lift than they are at others (e.g. half bench press vs full bench press). To overcome the differentiation in resistance, chains are used to accommodate changes in strength at different phases of the movement. Ultimately, your muscles will have to work harder because of the chains.

Here is what you can expect to feel while bench pressing with chains:

• Awkwardness due to the change in directional forces
• A progressive weight increase as each chain link is elevated off the floor

The following are instructions for performing the bench press exercise with chains:

First, secure the chains in place. Lie down on a flat bench. Ensure your hands are evenly spaced. Disengage the bar from the rack. Slowly lower the bar to the middle/lower portion of your chest. Pause for a second, then push the bar up, just short of locking your elbows. Exhale as you push the weight up. Repeat the exercise as needed.
