The Best Squat for Most Lifters: Back Squat

The back squat is the primary squat variation in most training programs for good reason. It allows you to lift more weight than other variations, which will ultimately lead to greater strength gains. Although it does require technique, it's one of the easier squat patterns for a beginner to pick up.

The Best Alternative: Safety-Bar Back Squat

Not For Everyone But Awesome: Front Squat

This exercise isn't for beginners or lifters lacking thoracic spine mobility. It's fantastic for developing lower body and anterior core strength, but it takes a bit of time to learn, and a lot of beginners royally screw it up. The traditional front squat requires a decent amount of mobility. Take a look:

Notice that the elbows are pointed down. If you don't have the mobility to do a front squat, you could use a cross grip or straps. However, most beginners have a hard time keeping the bar in place when doing these. If your gym has a safety squat bar, this would be your best bet to learn the movement.
