Take rest seriously when working at a High Intensity Interval Training.
Here at Nxt Level Performance we specialize in Kettlebell training see what researchers say about this type of training modality.
It’s funny how workout trends come and go, and how a centuries old piece of cast iron can inspire legions of exercisers in 2010. That’s the way it seems to be going for the good ol’ kettlebell.
These cannonball-shaped iron orbs with handles lifted in a swinging motion were developed by Russian strongmen in the early 1700s as a way to build strength, balance, flexibility and endurance quickly. And they do work well. If you want proof (at least anecdotal), rent the film epic 300 and take a look at the physique of lead actor Gerard Butler who plays King Leonidas of Sparta. Butler used kettlebells to prepare for his role in the film. But it’s not just Hollywood types who are getting into it. Kettlebell-themed fitness classes are now being offered at gyms across the country.
