As you hinge forward in the kettlebell swing, be sure that you drive your hips backward and do not allow your back to round out. Also, allow your forearms to touch the insides of your thighs at the bottom of each swing. Use your hips to powerfully drive your arms forward off your thighs to swing the kettlebells back up on each rep. This ensures that you’re doing the exercise properly by emphasizing a powerful involvement of your lower-body leg and hip musculature instead of just lifting the kettlebells with your arms.
