Whether you do just compound lifts or add arm isolation moves, both ways help reduce arm fat a little bit — and neither is better than the other.

After 8 weeks of lifting weights, whether you do chest and triceps together or alternate them with back and biceps, your arms and chest still get noticeably bigger.

Both kinds of weight training—whether you do one hard set or three regular ones—made young men’s triceps bigger and stronger after six weeks.

If you're new to lifting, doing big lifts like presses and squats is just as good for getting stronger as doing those plus extra isolated arm exercises.

Doing extra arm exercises along with big compound lifts like squats and presses makes arms a little bigger, but doesn’t make you stronger than doing just the big lifts alone.

If you're a guy who already lifts weights, doing full-body workouts five days a week will make your forearm and thigh muscles grow bigger than if you only work each muscle group once a week, after eight weeks of training.
