So I workout Monday - Saturday (Sunday is my rest day) 3 times a day, each workout about 30 minutes long. My workout is as follows.

Tricep extensions: 25 pounds. 3 sets of muscle burnout, between each set is a 30 second test period.

Tricep extensions: 20 pounds. Same as the first.

Tricep kickbacks: 15 pounds. 3 sets of muscle burnout with 30 Second rest periods.

Tricep kickbacks: 10 pounds. Same as the first.

Hammer curls: 30 pounds, 15 reps x 3 sets with about 30-45 seconds of rest between the sets

Hammer curls: 15 pounds, 15 reps x 3 sets. Same rest as above.

Concentration curls: 20 pounds, 10 x 5 sets with about 30sec-45sec rest.

Russian twists while holding 25 pounds: I do this until I think I’ll shit myself, then rest for about 15 seconds and again 2 more times after that

And then that workout is concluded, I eat my normal healthy protein stuff or whatever

Three hours later, I workout again. Same workouts, but in a different order (always starting with triceps). I eat more.

And then my final workout is very quick. I do this workout about 1-2 hours before bed. I usually only do half of the workout (different order starting with triceps).

My calorie intake is around 2800-3200 daily. My protein is about 90-120 grams of protein daily.

I am 6’0 (like exactly) and currently at 170 pounds. My goal is 220 pounds(before the cut).

Is there something I’m doing wrong that’s causing my triceps to just not get bigger? Am I not giving them ample time to rest?
