I didn't know how to word the question to actually fit what I wanted to ask, so if you can reword it into a more fitting title, please do.
Over the past couple of months I've done several weight-lifting approaches.
One muscle per day, this was a bit tiring since I was able to do around 5-6 exercises per muscle/area(chest, back, shoulders, arms, legs). After a month I switched to series, but still one muscle per day.
Monday: chest1, chest2, chest3, chest4, chest5
Tuesday: back1, back2, back3, back4, back5
and so on
By groups of muscles and in series (leg, chest/triceps/shoulders, back/biceps/forearms) but the way I did it was one muscle at a time, so 3-4 exercises per muscle, jump onto next muscle.
- Monday: chest1/chest2, chest3/chest4, shoulder1/shoulder2, shoulder3/shoulder4, triceps1/triceps2, triceps3/triceps4
- Tuesday: back1/back2, back3/back4, bicep1/bicep2, (you get the idea)
My current routine(barely 1 week in) its also by group of muscles but the difference is that each series consists of one exercise per muscle. This one has been the most tiring of all and for the first time in months I'm actually feeling DOMs(not hardcore ones but I feel them)
- Monday: chest1/shoulder1/tricep1, chest2/shoulder2/tricep2, chest3/shoulder3/tricep3, chest4/shoulder4/tricep4
Tuesday: quad1/hamstring1/calf1, quad2/hamstring2/calf2, quad3/hamstring3/calf3, quad4/hamstring4
and so on
What is it so special about this new approach that can get so tiring? I've been working out for a while, but I'm no expert so I can't explain it myself.
Hope my question makes some sense.
