These planks will really work out your biceps and triceps area, along with your core and stability as well.
Do as many levels as your body allows you, remember to breathe properly and do some stretches after a cool down period of 5 – 10 minutes.
Disclaimer: Do not perform these exercises if you have any injury, get rehabilitation first. If you get short of breath, feel fatigued or tired during any of these workouts, stop and take a break. Consult a doctor/trainer if necessary before starting any workout session. Children should do them under supervision of an adult.
