Whether you're enjoying a session in the home gym, local park or somewhere a little more commercial; make sure you're wearing one of these.
Check out the blog of elite conditioning and combatives group Team Ruthless. As you can see from the writings of Lady Hardbody (a dedicated follower of the Team Ruthless training philosophy), the daily workouts are more than enough to get you breathing hard. 250 burpees in half an hour? Just warming up.
For a taste of the action, head over to the Team Ruthless videos page. Enjoy.

"Sonnon is without doubt one of the top conditioning coaches in the US, the thinking man's coach. He is the hologram man. Try and hit him and he disappears."
