I like short gym sessions of 40-50 min tops.
One compound movement per training going heavy but not below 6 reps in the end. Been doing very good so far. For instance, today I got 5 mins of cardio to get the blood flowing, warm up joints and ligaments, then I did 6 sets of squats finishing at 500 pounds for 8 reps.
then i do 4 sets of 4 exercises in a circle with no rest in between exercises - today they were neck bridges, forearm curls, shrugs with kettle bell front shoulder trowing shit.

then i take my shirt off for them bitches,
