These are a great way to add some stretching with slight loading to your program, or you can add these to a long complex of Grappler movements using the bar or very light weights.
You'll see many Grappler exercises here and the way we often use the Grappler is through a circuit for extended time periods or via heavy pressing motions.
With the flys, you want to keep a slight bend in the elbows and stop when the hands are approx. 12 inches apart.
Keep the movement rhythmic or slow on the way down and explosive on the way up.
Performed with moderate weights and higher reps, this is a great muscle builder to the upper body.
