MuchMoreThanMuscle saidI would do them on back day so that way you can do legs on another day to stimulate the leg muscles on more than one day. Many people support the theory of working legs in some way on more than one day. They are the biggest and densest muscles compared to the upper body and generally are faster twitch muscle fibers that can take more work.
In any case, the neural stimulus of working the legs either directly or indirectly (with power deadlifts on back day) should help support overall growth. That is what I would do.
Today I did back and chest and for my back routine I did:
One warmup set with one plate on either side of an Olympic forty-five pound bar and then did four working sets in addition.
Warm up was one set of ten reps followed by four sets of eight to six reps for my working sets. I do less repetitions for deadlifts since they work so much of the body all at once.
Then followed by four sets of seated rows for ten to eight reps.
Finished with bent over single arm rows with dumbbells.
Tada! Done! I technically did a total of thirteen sets (one was warmup for deadlifts).
Then I move along to chest.
thanks, i did my chest w/o tonight but next week i'll re-introduce deadlifts on that day. ( i used to do it that way ).
i see you do back before chest.. any particular reason? i usually do the opposite, lol , without any particular reasons.
i've also combined both like sets of chest/back/chest/back ... but not anymore.
