“To perform a hill climber, get into plank position and raise one knee up to your chest at a time, ensuring your back remains straight at all times. Perform the action one leg after the other and as fast as you can.”
He commented: “The original ball slam is a great way to elevate the heart rate quickly whilst developing core strength, positioning itself as a fantastic calorie burner.
“Stand with your feet hip-width apart, squat down keeping your back straight, drive the ball upwards with your arms fully extended and the ball overhead, then accelerate downwards back into the squat position slamming the ball into the ground on the way down.
“Try and catch the ball on the bounce and keep it fast paced for a great cardio and strength workout.”
