Shaun T, the man behind Instanity, reported to be the hardest fitness program ever, has revealed the one workout you should do every day especially when you don't feel like it.
He may be known for his super-ripped shape, but there are days when even he doesn't feel like a full regiment.
So he recommends doing the push-up and plank, the Daily Mail reported.
"The push-up and plank will change your life," said the 39-year-old is quoted as saying by the Daily Mail.
Best of all you don't require any equipment or have to leave your home.
Shaun said the planks give your whole body a workout as it uses muscles from all over.
"Holding a plank works your your shoulders, your chest, your core, your butt, your calves," he told Business Insider. It also strengthens your core, supports postures and improves balance.
