The best of online fitness

10 Jillian Michaels

If you thought YouTube solely existed for the perusal of funny cats and Lonely Island music videos, you’re wrong. It’s also a great workout tool – and a lot of the offerings are free (yes, and legal). Jillian Michaels is one of the best – a veteran of the fitness DVD world, she was the star of The Biggest Loser in the US, and her videos are a great introduction to the world of fitness – and boast over 10 million views.

Why we love it: it’s all very Jane Fonda – pure, fun aerobics.

Cost: Free
