Should/could I be doing more to gain muscle?
For the past three or four years, I mainly focused on toning my body, with a couple of 6 month periods of focusing on gaining muscle, but this year I'm going to try and mainly focus on building muscle. My overall goal is gaining muscle and strength, both for my own self-confidence and to try and be more healthy and active.
For my routine, I go to the gym about three or four times a week, two or three sessions working on either chest or arms, with one session being strictly cardio and glutes (also recently started working on core slightly). I use Optimum Nutrion creatine (twice daily except on weekends) and whey protein (used during my non-cardio workout. I do 4 sets with incremental weights, doing about 15 reps each set.
The pictures here are as follows: 1st pic, taken an hour ago. 2nd pic, taken April 1st this year. 3rd pic, taken October 23rd last year.
Is there anything I should/could be doing to improve? Whether that's doing more sessions each week, focusing more on one muscle group than another, or anything else. Any and all advice and recommendations is appreciated. Thanks gym lads.
