If you have a spare five mins in the gym give this a go… the idea is to test and improve your balance and core stability skills. You’ll need to be able to hold a full plank position (on your toes) on the floor for 30 seconds before trying this
Put both of your hands on the medicine ball and hold plank position for 30 seconds.
Once you’ve mastered the standard plank hold, progress by lifting your right leg 1 inch off the floor, pause for a second, and rest it down. Do the same with your left leg and repeat ten times on each leg alternating between left and right as you go.
Once you can do the alternate leg lifts consistently, progress onto mountain climbers – hold the plank position with hands on the medicine ball and bring your right knee up towards your chest, keeping your knee close to the floor, and then return to plank position. Repeat with your left leg – build up to ten repetitions on each leg alternating as you go.
Progress the mountain climber by using a sliding disk under each foot.
