This exercise targets the extreme lower pec line, which can be extremely difficult to isolate effectively. It is a movement that should be done with light weights as it is more of a finishing movement rather than a mass building movement.
How to incorporate this exercise into your workouts:
Do these at the end of a chest workout to finish off the muscle as you can’t and shouldn’t use much weight with it.
1. Not keeping a bent-over position
If your upper starts to become more upright, you will start to work more of the lats and triceps. Since the goal is to work the pecs, keep your upper body bent over.
2. Using momentum
It is critical that you do this exercise slowly and squeeze the lower pec area hard. Using momentum will totally remove the tension off the muscles.
1. Start in a more upright position then bend over as you do the exercise
By starting in a more upright position and bending over as do the movement, you will improve the leverage of the exercise somewhat. This may allow you to use a little more weight or get a few more reps.
