Burn 150 Calories in Just 10 Minutes (Warning: This Workout Is Hard!)

Choose the heaviest kettlebell weight you can use with correct form. For reference, I use a 26- or 35-pound kettlebell.

• Stand with your feet wider than hips-width apart, toes slightly pointing out. Squat down, and hold a kettlebell with both hands between your legs. Make sure your back is flat and your abs are engaged.
• As you inhale, press into your feet and explode up, straightening your legs and swinging the kettlebell in front so your hands are in line with your shoulders. For a more advance version, swing the kettlebell up overhead.
• Exhale, and with control, come back to the starting position, allowing the kettlebell to swing back between your legs.
• This counts as one rep.
