im considering changing to a push/pull/legs routine so each muscle group gets 6 or 7 days rest. im doing a ABA type split where each muscle group gets worked every 4 days but im struggling, i just dont seem to recover quick enough and im eating loads and my weight is slowly creeping up so i know im eating enough, i put loads of effort into lifting and by next workout try and beat the previous etc but recently im finding it tough to progress. would it be worth me trying a push/pull/legs type routine so each muscle group gets more rest? the thing that puts me off is ive always read that these splits are only effective if you are on steroids, which i am not?
