Burpees are a form of tough love for many-but they are wonderful for improving the endurance/power output of a fighter, and you can do them anywhere. I have always loved them and want others to get better at them-here I am combining both specific and general strength to feed the fire for the Burpee at the end:
20 Grappler's Twists
4-6 HEAVY(something that takes effort but not injury-it took me almost a month to get up to using a 50lb one) DB Clean/Press-4-6
Heavy Two Arm Swings-8-10
A powerful combination that produces results for the cage and beyond. Thanks to Eric Guttman whom I met at the Superhuman Training Event, of ericguttman.com. His Extreme Military Fitness programs are worth checking out!
