The goblet squat works your legs, hips, core, and erector spinae muscles. It’s really similar to the front squat because the weight is concentrated on the front side of your body. You can use a kettlebell or a dumbbell when doing this exercise.
There are two ways to hold the weight. You can either wrap your thumbs under the handle of the weight, or you can cup the weight with both of your hands. In either case you want to keep the weight on your upper chest as you go down in to the squat.
The technique on this lift is basically the same as the front squat. You want to sit back and drive the weight through your heals. Try to get your hips below your knee level. The challenging part is keeping your chest up throughout the movement, because the weight will try to pull your chest down.
