Chest flies are excellent for strengthening and building the pecs in addition
to stretching them. The Total Gym chest fly does everything that standard dual
cable cross chest flies do with the addition to working your core muscles. A
bonus for using the Total Gym for chest flies is you can instantly transition
into chest press and vice versa. As with all Total Gym exercises increasing the
angle of the Total Gym bench increases the difficulty but in the case of
the Total Gym chest fly, you can straighten out your arms a little more and
spread them further apart to increase the demand for the chest muscles. Since
chest flies isolate the pecs, they are not as important as compound exercises
for those involved in weight loss programs, but are invaluable for those looking
to build and tone the pec muscles.
