I am 25 year old personal trainer been lifting since I was 18 but doing only been doing 5/3/1 for the last 2 years and have made outstanding gains from this program so thank you Jim. Iv followed the program exactly as written and only changed the assistance exercises depending on weaknesses and goals at the time. I have been using BBB for mass and Hypertrophy and SST to push my strength work up as well as truimvirate to keep it fresh.
However my goal for the summer is to put on some lean mass so I thought I would give the BBB 3 month challenge another go last time tried it gave up on the 70% month. This time I will smash it.
In terms of aesthetics my arms have always been pretty small especially in my triceps. I absolutely hate doing skull crushers of any kind my question is Jim what exercise can I put in my upper body day for the best mass gains in triceps that wont hinder the BBB 3 month challenge?
