A friend told me that I should NEVER train L-flys to muscular failure.
yesterday I read in Mike Robertson's great article "shoulder the load":
"So after youâ??ve started off light and gotten these muscles working, train them like anything else! Iâ??m not saying you want to do heavy singles, negatives, or the Weider forced reps principle, but you should still periodize your training like you would any other muscle group."
And after these lines I wondered if it's ok to train to muscular failure (without any cheat reps)?
what do you think?
thanks in advance!
