"After burn effect" workouts, basically you keep burning fat and gaining muscle i believe 24 hours after you do it, stuff like bench pressing.
what I would recommended:
Concentration curls
Hammer Curls
Bench pressing
-- The first one really concentrates on your biceps( the muscle un the top part of your upper arm)
the second one is for biceps but works on your triceps too, and a bit on shoulders
Bench pressing works mainly on your chest but does work on your shoulders and triceps also.
For abs, weighted sit ups.
You should also search different techniques/moves and switch it up a bit, it grows muscles faster. and if your really going at it, get sufficient amount of protein.
Always remember to warm-up before starting and streching, so maybe do some cardio. Also, dont underestimate the basic things, push-ups, pull-ups, etc.
get sleep, its the time when your body focuses completely on regenerating.
Drink milk and other things that helps you to heal your muscles.
Hope I helped
