This Kettlebell Abs Workout Makes You Train Harder And Smarter

Kettlebells are one of the most effective pieces of kit you can use to add resistance to your abs workouts. They are less cumbersome to wield than other free weights thanks to the large handle, so you can grip them easily during a variety of exercises.

Once you have your kettlebell you need the right workout, and the best abs workouts will involve a mix of moves that work your core from different angles. This workout from Ashton Turner, co-founder of London's Evolve 353 gym, certainly does that, targeting your rectus abdominis (the sheet of muscle that makes up your six-pack), side abs and lower back. It also uses unilateral exercises to keep your core working throughout the moves to ensure you don’t lose your balance.

“Single-sided moves make you unbalanced so your body has to work harder to keep you stable,” says Turner. “Any overhead move, like a windmill, will also require good core strength to stabilise your spine.”

Kettlebell Abs Workout Instructions

Do three sets of 10 reps for each exercise, resting for 45 seconds between sets and 90 seconds between exercises. For single-sided exercises such as the side press, do two sets on each side, alternating sides each set. 

To keep progressing, add a rep to every set each time you train, until you’re doing 15 reps in each set. After that, use a heavier kettlebell and go back to doing ten reps.

Lie on your back and hold a kettlebell in each hand by your chest. Straighten one arm and push upwards so your shoulder leaves the floor and you twist your torso. As you lower that kettlebell, extend the other arm to create a smooth rhythm.

Expert tip “Lying on the floor reduces the instability, and therefore the risk, of the exercise,” says Turner. “I get people to think about imprinting their lower back on the floor. That will help you to avoid overarching your lower back and switching off your abdominal muscles.”

Sets 2 each side Reps 10 Rest 45sec, 45sec, 45sec, 90sec

Start with the weight above your head and your feet wider than shoulder-width apart. Your weight distribution should be biased towards the side that’s holding the bell. Look at the bell and, keeping your eyes on it, lower your torso until your hand touches the floor.

Expert tip “Windmills look intimidating but they are an excellent move for building core stability and shoulder stability because they require a lot of control,” says Turner. “They also give you a good hamstring stretch.”

3 Side press

Sets 2 each side Reps 10 Rest 45sec, 45sec, 45sec, 90sec

Start with the kettlebell at shoulder height. Brace your core and lower your torso to one side while simultaneously straightening your arm. Aim to keep the kettlebell in place so that it barely moves - instead, your body should move away from it. From there, reverse the move back to the start.

Expert tip “This is a great obliques – side abs – exercise because you have to stabilise your torso as you push the weight away from your body,” says Turner. “As you get lower, the intensity of the exercise increases and your centre of mass changes. That forces you to think about the constantly changing kettlebell movement and instability as you go through the exercise.”

Sets 3 Reps 10 Rest 45sec, 45sec, 90sec

Start by sitting down with your knees bent, holding two kettlebells overhead. Slowly lower towards the floor while bringing the kettlebells down to your chest. Contract your abs to raise your torso while simultaneously extending your arms.

Expert tip “Once you’re sitting up straight, tuck your pelvis under and, as you lower, ‘roll through’ your spine so you’re trying to make contact with the ground one vertebra at a time,’ says Turner. “Going slowly on this move will make your abs work harder.”

5 Plank drag

Get into a straight-arm plank position with your body in a straight line from head to heels, with a kettlebell positioned on one side of your body. Reach under your torso to drag the bell across to the other side. Switch hands and repeat the move.

Expert tip “This is great way of making the plank more interesting,” says Turner. “The wider you take the kettlebell, the hard it is to do. You can also try raising the kettlebell off the floor slightly to turn it into a modified reverse flye.”
