I am a student and am 18 years old. I’m 6 feet tall and weigh about 72 kg.
Although I am mainly quite thin, most of my fat is accumulated around my waist and stomach (my chest and arms are skinny and ribs are partially visible).
Do you have any tips on how to gain mass overall on my body that is on the chest, stomach, arms, legs etc?
Follow a full body, strength training routine – starting strength and stronglifts 5×5 are awesome beginner programs. It looks roughly like this:
Workout A: 3-5 sets of 5 reps
Bench Press (or chest machine if beginner)
Bent-over-row (or back machine)
Deadlifts (or leg press machine)
Workout B: 3-5 sets of 5 reps
Overhead Press (or shoulder machine)
This isn’t the exact routine. Give it a google search, grab some popcorn and read up!
Highly recommend you learn to do the full compound lifts with barbells,
there are plenty youtube tutorials. Check out the one’s by Mark Rippetoe and
the art of manliness.
