Squats.

Body weight squats are a great exercise you can do anywhere and a fantastic way to learn proper technique. Start off your squat workouts by lowering yourself only a foot or so. Then work up to deeper squats as your muscles become accustomed to the exercise.

• If you're feeling a bit advanced and in need of a more intense workout, grab two 2-liter bottles filled with sand and try performing squats while holding one in each hand.

Bodyweight squats. From a standing position, squat down and stand back up. Do as many as you can and try to go all the way down until your thighs are parallel to the floor. If that’s too difficult, grab a doorframe to pull yourself back up.

Jump squats. These are similar to the bodyweight squats, but instead of just standing up, you’re going to jump as high as you can, land softly, and repeat. Do as many as you can. This is a tough one.
