1. Overhead Squats
This type of squat is highly effective when you want to increase your arm strength and improve your balance and mobility. Everything you need to do to perform them is the same as with regular squats. The only difference is that you need to hold the barbell overhead while you squatting.
2. Hack Squats
If you’re looking for something that would concentrate more on your thighs and quadriceps without causing too much spinal compression, then try hack squats.
Take the barbell into your arms while holding it behind your back and keeping your chest straight and back arched. Squat down, raise yourself again and then repeat the same thing again.
3. Zercher Squats
Use this squat variation to strengthen your torso, core, hamstrings, and glutes. Perform it by hooking the elbows under the bar and move it upwards. Squat down and till your elbows are below your knees and then raise up.
