if thats so i have been over training for years. I hit every muscle group 2x ew split according to what i have worked the day before. depending on how im feeling i wil maybe fit an extra bi or calve workout. And there are those weeks where i feel like resting 2 days in a row to get a good recovery. But im a sedentary dude.
overtraining is different for everyone. i warmup full body with bodyweight every morning and night 30 minutes or so. during that time i do 100+ reps each exercise x 5 to hit the whole body and core plus some cardio from sprints usually. i am always increasing the difficulty of the exercise or the number of reps per set and or total sets. pushups are handstand. pull ups are weighted muscle ups. shit like that.
my regular workout takes about 2 hours i don't rest much and as a base i hit the major lifts full body low weight for high reps high sets. for example bench is 265 for 15 sets of at least 10 reps. i do everything twice a day almost all of the time, from 7-9am and from around 8-10pm my quote unquote split goes like this:
mon:upper body very high volume
tue: lower body very high volume
wed: extra cardio and core
thur: upper body high weight lower volume
fri: lower body high weight lower volume
on the weekends i'm usually at public parks doing bodyweight workouts on bars with other bodyweight and plyometric stuff and playing sports. usually 5+ hours both sat and sun.
i take a day off once in a long ass while and usually not so much by choice.
this is how i train when i'm not actively playing a professional sport where my training is more or less controlled by outside parties. although the warmups and stuff like that i been doing every day for probably 10 or so years.
