Hey Eric, thanks for the reply. I think the reason i'm only doing 15 sets in that amount of time is b/c im working out at home and have to change weights and then screw them back up again but yeah, ill be more conscious of that next time. My workout right now is the following (the number at the beginning refers to how many sets and I aim to do about 6-8 reps per set. When I go over that amount, I increase the weight):

Sun&Wed
Chest
2 Barbell Bench press
1 Inc Barbell Bench press
1 Dumbbell Bench press

Shoulder
2 Military Press with Barbell
2 Upright Rows

Trapz
2 Seated Shrugs with Barbell

Triceps
2 Close grip bench press
1 Lying Overhead raise


Mon&Thu
Glutes
2 Hack squat
2 Split squat
1 Glute curl
1 Hip Abduction

Calves
2 Calf raise

Biceps
2 Standing dumbbell curl
1 Hammer raise

Back
3 Pullups
2 Barbell rows on bench

Before this, I was doing HST and pretty much following the standard workout. I have made gains but I seem to hover around 160 even while making lots of strength gains.
