Is it worth adding rows to the GSLP? I'm loving the program (adding weight on the bar each workout) but I don't feel like I'm doing enough work at the gym, haha. It really feels like I should be doing more, heh.
Indeed, you could. Great thing about Grayskull is the main lifts are so gradual in increasing that you can add accessory work, even as a novice. For example,
Monday: Bench, Rows, Squat
Wednesday: Press, Chin, Deadlift
Friday: Bench, Rows, Squat.
I, as does Johnny Pain, the creator of the program, enjoy Chins on the Press day. After hammering out 5+ reps on press, it's good to work the lats and biceps.
Do rows on your bench day, 3 sets of 5-10. Start light and gauge your weight. Also, if you'd like, you can do bent over dumbbell rows.
Johnny's program for guys that are going for a more hypertrophy look goes:
Monday: Bench, Curls (2 sets, 10-15 reps), Squat, Neck Harness (4 sets 25 reps)
Wednesday: Press, Weighted Chins (3 sets, 6-8 reps), Deadlift, Neck Harness
Friday: Same as monday
It's pretty flexible.
As a side note, neck harness work will make your traps look pretty solid after a month or so. I enjoyed putting an inch around my neck.
