1# how do you know about my work capacity
2# depending on what set/rep range you do you can do both in one training session. its all to do with work capacity and endurance........i ranges from person to person. I myself have trouble with higher rep range stuff.....but can pull off many sets at a lower range.
3#you dont know me. I dont train both in one day. I used to.....but gave up due to finding a better program. I am a powerlifter.....and train as an olympic lifter as well (you cant say i dont have a high work capacity if i can last a 2 1/2 hour training session with squats and olympic lifts)
4# i work a labor job lifting crates for 8 hours a day......and my back doesnt get tired. i have a high work capacity.
IM NOT TRYING TO IMPRESS YOU, IM NOT TRYING TO BE MORE OF A MAN, im just stating the truth.
many of the worlds best powerlifters train 3 compound movements a day......i dont hear them complaining......just breaking records.
Try increasing the rest between sets.....what percentage of your 1RM are you working?
