20 to 25 minutes seems more accurate depending on how much wind I have between exercises. If I sat there and totally rested between exercises I could spend more time doing my workout. I like pushing myself without rushing...seems to boost fitness that way.
stats
6'3
225
7% bodyfat (was 4.6 last summer)
max's (has been a few months since tested 1rm but this should be close)
bench 375
squat 510
thats the only two exercises I do 1rms on because of past problems with shoulder joint and lower back..can still do decent weight with everything else but I try to train smart and as injury free as I can.
I know Im not the strongest out there but Im not a powerlifter, just trying to gain muscle..my goal is 245 staying around 7%bf.
I should tell you I just turned 40 and Im in the best shape of my life. Ive been training since 20.
