On plenty of occasions body weight is all I have to work with and my workouts have never been better. Here are a few examples of ways to target multiple areas, using nothing but your own body resistance and power.
Start in a basic lunge position to bring power into the movement. Bring the back leg up and perform a small hop with the front leg to combine a cardio element with a massive leg burn.
Three for One
Work the non-mirror muscles, meaning the backside, hamstrings and triceps, in one exercise. Start in a bridge position with hands and feet both parallel and facing forward. Drop the buttocks down to the floor, forcing you to flex at the ankle and bend at the elbow. Once the buttocks hit the floor, come back up to bridge, bringing the feet back down to the floor and straightening the elbows.
Start in a basic side plank and hold for 10–30 seconds. Next try and bend the top knee and bring it up to touch the free arm at the elbow. This adds another movement for obliques and increases core stability.
If you really want to push the envelope, bring the top leg straight across in front and have the free arm attempt to touch the toes. Alternate between the knee bend and the straight leg, working evenly on both sides.
