Stand holding a light kettlebell by the horns close to your chest. This will be your starting position. (If you don’t have access to a KB – you can use a dumbbell or medicine ball.)
Squat down between your legs. As a runner you don’t need to focus on range instead good technique should be prioritised.
Keep your chest and head up and your back straight.
Imagine you’re pushing the floor apart with your feet to help engage your glutes.
