I agree that flyes lack some peak contraction, however I always consciously do some isometric posing contraction at the top of the movement and hold that for 1.5 - 2 seconds...
I think i am gonna superset flyes with cable crossovers to see what is does.
Lately I am really into Giant sets and the latest chest routine is free weights only and it does seem to pay off, especially for the area in between the upper and lower chest that lacked development (i contribute that to doing flyes and dumbell presses at a LOW INCLINE ANGLE ( 20-30 degrees) as opposed to the standard incline 45 " benchpress....
some remark of ronnie coleman inspired me to write the routine : "i always choose a weight that i can do barely for 8 reps , but in never stop unitl i get 12.."
Offcourse we are talking forced reps with spotter, drop sets or rack sets here, anyway we use this concept for the following chest routine :
Giant set 1:
- incline benchpress 1 * 8 (and continue this set to 12 somehow)
- low incline dumbell press 1 * 8 (12)
- wide dips with bodyweight (you probably can do only 5-10 reps as the chest being exhausted , thats good the lower pecs have to work especially hard now)
- low incline flyes 1 * 8 (12)
take 4 minute break, really you need it!
Giant set 2:
- incline benchpress 1 * 8 (12)
- low incline flyes 1 * 8 (12)
- wide dips with bodyweight
- low incline dumbell press 1 * 8 (12)
Giant set 3:
- incline benchpress 1 * 8 (12)
- low incline flyes 1 * 8 (12)
- wide dips with bodyweight
- low incline dumbell press 1 * 8 (12)
Done ! Note, free weight only routine and no flat benching, i guarantee your will find this a boobbusting workout
