DO exercise at your home

1. Abdominals

Abdominal Crunches

Lie down flat on your back with your knees bent and your feet on the floor. Hold your hands wherever you feel comfortable (on your chest or beside your head - just be sure you don't pull on your head). The typical crunch is taught by instructing you to simply roll your upper torso forward. This is fine to start with. To increase the effectiveness of the crunch movement, push your chest and head up towards the ceiling pushing your lower back flat onto the floor. Your anatomy will automatically cause you to follow a crunching pattern. Hold at the top of the movement for a second and squeeze hard.

2. Biceps

Dumbell Curls

• Stand with your knees slightly bent, arms at your sides, holding your resistance bags or two dumbells in your hands.
• The curl movement happens only at the elbow. With your upper arm pinned at your side and bending only at the elbow, lift the weight up to shoulder level.
• Your palm should be facing forward all the way up and all the way down.
• Squeeze hard at the top then lower slowly.
• Do the same with the other arm, alternating back and forth.
