Train your core in just three moves with this trainer’s efficient kettlebell workout

Woman performs a kettlebell swing.

This three-move kettlebell workout won’t take up much of your day, but you’ll certainly feel the burn afterward. 

The exercises recruit multiple muscles across your body, while also challenging your core. You can do the quick routine on its own or tag it onto the end of your usual training session. 

As the repetitions (reps) are on the higher side, choose a kettlebell weight that you find challenging, but make sure it’s not so heavy that it ruins your form or stops you from completing the required number of reps. You might need different weights for different exercises, as some of the moves target smaller muscles.

The workout

• Kettlebell swing: 3x20
• Single arm crunch: 3x10 per side
• Russian twist: 3x15 per side

Reps: 20 Sets: 3

• Place the kettlebell a couple of feet in front of you. Stand with feet shoulder-width apart. Bend your knees and bend forward to grab the handle of the kettlebell with both hands. Keep your back flat and engage your lats (muscles across your back).
• Pull the weight between your legs, then drive your hips forward and explosively swing the kettlebell up to shoulder height with arms straight in front of you. 
• As the weight falls, squat and drive your hips back, allowing the kettlebell to swing back between your legs. That's one rep.

2. Single-arm crunch

Reps: 10 per side Sets: 3

• Lie on the floor with your legs out straight, holding a kettlebell in one hand, with your arm straight and held in the air overhead 90° from your chest.
• Crunch up into a seated position, while moving your shoulder so the kettlebell remains directly over it.
• Slowly return to the starting position.

3. Russian twist

Reps: 15 per side Sets: 3

• Sit on the floor, with your knees bent and heels on the floor (you can also keep your heels elevated). Hold a kettlebell on your chest. Lean back at a 45° angle and engage your core.
• Slowly rotate to one side, twisting through your core and taking the kettlebell towards the floor by your hip. 
• Return to the center and repeat on the other side. If this is too difficult keep the heels in contact with the floor.
