Best arm exercises: plank to push-up
Start in a high plank position (on your hands instead of your elbows) with your arms directly underneath your shoulders and your core muscles engaged.
Lift one arm up and place your elbow down, followed by the other arm so you are on your elbows (traditional plank).
Return to starting position by lifting one elbow up at a time and placing your hands back in the original position, until you are back to a high plank position. Do as many as you can in two minutes.
Best arm exercises: dumbbell curl and press
Works: biceps, shoulders
Stand holding both dumbbells next to your hips with feet shoulder-width apart.
With palms facing toward your body, curl arms up to your shoulders.
Continue to push both arms up toward the ceiling, pausing for a second when your arms are fully extended before returning to starting position.
Do 8-12 reps.

Best arm exercises: dumbbell kickback
Works: triceps
Start by holding dumbbells in both hands; bend forward from your hips, maintaining a straight spine and keeping your chest up. Keep neck aligned with your back so you are gazing at the floor slightly ahead of you. Bend elbows, keeping your upper arms alongside your body.
Extend your arms one at a time behind you and squeeze your triceps muscle for a moment before returning to starting position.
Do 8-12 reps on each side.
