Hmm, so here's a random question for the fitness mindshare... When I'm doing a workout routine that is focused on two different muscle groups, is it beneficial or detrimental to either group if I alternate between exercises? For example, I do a back exercise (all 3 sets), then do a bicep exercise (all sets), then do a different back exercise, followed by another bicep exercises, etc. etc.
I've been debating switching to a routine where I do all of one group's exercises before moving onto the other, I'm just looking for some candid advice from real people. Google'ing for these kinds of answers just pisses me off; so many sponsored sites, people with agendas, shit to sell, etc.
