Some exercises are complex and more obscure, and perhaps that’s why you’ve never heard of them. Others just get left by the wayside from the sheer amount of exercise possibilities out there to target each muscle. Each of the following five exercises is amazingly effective when it comes to getting your body into great shape. Likely, they are not yet part of your workout routine, but it might be wise to add them.

Overhead Squat

Everyone’s heard of the standard squat, but ramping it up a bit can never hurt, and the overhead squat does just that. For this move, you’ll need a fairly light Olympic barbell. Use an overhand grip that is very wide along the barbell, and place your feet shoulder-distance apart. Your chest should be out and your back flat. In a standing position, extend your arms fully, with the bar just behind your head. Now squat until your thighs are parallel with the floor.

Russian Twists

The Russian Twist is a great ab move with side-to-side movement so your abs get a full workout. Sit on the floor and grab a weight or medicine ball with both hands and your elbows slightly bent. Bend your knees about 90 degrees and lift your feet off the floor. Move the weight from one hip to the other back and forth continuously. Your shoulders should be rotating, but try to keep your legs as still as possible. Aside from strengthening your core, this move also stabilizes your muscles.

Reverse Plank

The plank is popular, but most people have never heard of the reverse plank, an exercise that strengthens your hamstrings and lower back, while also stretching your chest and shoulders. Begin sitting on the floor with legs extended. Place your hands behind your hips just wider than your shoulders, fingers pointing toward your toes. Raise your hips and core off the ground with your gaze upward and neck relaxed. Your body should be in a straight line. Hold for 30 seconds, rest 30 seconds, then repeat once.

Jumping Jacks

Jumping jacks are a cardio exercise that workout your upper body, lower body, and core. Because they are so easy and require little coordination, your engagement increases. Plus, there are lots of ways to spice up traditional jumping jacks, like moving your arms side to side rather than up and down.

Glute Bridges

Glute bridges are often abandoned because they aren’t so easy to do right. However, when they are performed correctly, they will get your butt in shape and fast. Lie faceup, knees bent, feet flat on the floor. Arms should be at your sides, palms down. Lift your hips off the ground so your knees, hips, and shoulders are in a straight line. Squeeze your glutes tightly while flexing your core, holding for several seconds before slowly lowering back to the ground and repeating.
