If you’re wondering about the best exercises to perform during the holiday season, you don’t have to look any further. For about $50, you can buy a pair of wooden parallette bars (mini-parallel bars) for body-weight strength training. For the most effective results, follow these five parallette moves to develop a bulletproof core.

Plank To Push-Ups

This move will help you get stronger. Start in a plank position on the bars with your elbows bent at 90 degrees. Hold this position for a few seconds. Then, lower your chest to be parallel with the top of the bars. Hold for 90 seconds. As you become stronger, you can take the push-ups deeper.

The Simple “Dips”

This is one of the easiest moves, but it works your whole body. It’s worth it. Lift yourself off the floor using the bars. Fully extend your legs, so your body makes an L-shape. Lower your hips toward the floor, then press back up. You’ll feel the burn with this move.

Forward Plank With A Knee Drive

If you can’t already tell, parallette bar moves love plank positions. For this move, begin in a standard plank position, with your hands planted firmly on both bars. Lean forward until your shoulders are over your hands. Then, squeeze your abs while you drive one knee upward to your chest. Alternate with your other knee and repeat.

Tuck Planche

Again, begin in a plank position, with your arms fully extended. Rock your weight forward onto your shoulders. Then, tuck your legs up toward your chest. The goal of this position is to have your pelvis parallel with the ground. Hold for a long period of time, and work towards holding for a longer duration each time.

V-Tuck To Kickback Push-Up

This move is a combination of many other positions. To begin, sit in the middle of both bars and lift yourself off the ground, fully extending your arms. Then, bend your legs, drive your hips upward and forward to form a V-shape. Hold for a few seconds, and then slowly reverse the position to kick your legs behind you to drop down into a push-up. Repeat and you’ll feel the burn.
