Embrace instability with this challenging circuit that forces your core to stay strong – all you need are a pair of dumbbells and a gym ball.

The foundation of any home gym set-up should be a set of dumbbells and a gym ball. You can target any body part in a variety of ways, increasing your chances of losing fat and gaining muscle. 

Dumbbells allow you to fatigue your muscles easily within your desired rep range, helping to build new muscle. The fact that you hold one in each hand gives you balanced muscle growth and develops your stabilising muscles because you’re forced to control their movement. 

A gym ball is excellent at increasing the instability of an exercise, which will improve your core strength. The greater the instability, the harder the exercise. For that reason, a gym ball is a great tool to use in conjunction with a set of dumbbells, because you’ll struggle to complete your sets of unstable exercises, even if your heaviest dumbbell is 10kg. 

How to:

  • Complete 12-15 reps of each exercise.
  • Once you’ve completed the reps for one exercise, move onto the next with minimal rest.
  • Once you’ve completed the final exercise, rest for 90 seconds.
  • Do the circuit a total of 4 times.
