Upper Body Circuit Training Exercises.

Dumbbell Exercises
There are dozens of upper body circuit training exercises you can do with dumbbells. Examples include biceps curls, lateral raises, alternating shoulder presses, triceps extensions, front raises, single arm rows.
Push-Ups
To make regular push-ups easier (remember you need to sustain them for 30-60 seconds), keep your knees in contact with the ground.
Wide Push-Ups
Same as a regular push-up except spread your hands to wider than shoulder width.
Diamond Push-Ups
Same as a regular push-up except place your hands together and make a diamond shape with your thumbs and forefingers.
Plyometric Push-Ups
Same as a regular push-up except as you extend your arms push up explosively so your hands leave the ground. Then allow your elbows to bend slightly to absorb the shock as you land. Lower and repeat. A variation of this exercise is to quickly clap your hands as they are in the air.
Bench Dips
1. Sit upright on the edge of a sturdy bench and place hands hip width apart, palms down, fingers pointing forward and gripping the edge of the bench. Place heels on another bench with legs out straight in front of you.
2. Start position: Slide glutes off bench with elbows slightly bent.
3. Lower body by bending at elbows until elbows are at 90 degree angle. Return to start position.
