3. Improved balance and sports performance.
How good is your balance? Maybe it needs to be improved a bit? Then do planks! There are side planks for those who are advanced enough to accept the challenge. Another variant is to do planks on a stability ball. It might take some time to become an ace but, trust us, the results will stun you. What you will feel is that your whole midsection has become toned up and strong. Your lower- and upper-body muscles will also start transforming. In general, you will feel fit, trim and full of energy.
