To get a lean body, you need to follow a body building program which consists of a good diet and an exercise routine.
The exercises you should include in your routine are:
1. Dumbbell wrist curl: Sit on the edge of a bench with your wrists placed on the edge of your knees and palms facing upwards. Hold dumbbells in your hands and let them be lowered all the way.
2. V sit: Lie on your back with straight legs and arms by your side. Lift your legs, trunk and arms at the same time with legs straight. Maintain this position for a minute with deep breathing.
