There's no real substitute for partner training in groundfighting, but there is a way to train full speed, full power and no-holds-barred, even without a partner.
The secret is Mark Hatmaker's revolutionary floor bag workout. Using an ordinary heavy bag (not a grappling dummy that costs four times as much), Hatmaker teaches you how to realistically simulate the weight and resistance of a real opponent as you practice dozens of groundfighting moves. He starts with a variety of lifting exercises that will develop the grip and specific strength you need to dynamically maneuver an opponent at close range. He then teaches you how to tune your grappling skills on the bag, using it to drill critical skills like the cross-body position, head-and-arm position, lateral press and top body scissors, as well as specific submission techniques and combinations. Finally, Hatmaker shows you how to use the heavy bag to practice techniques that are too brutal and dangerous to drill with a live partner, including punishing power throws and slams, chokes, stomps and hamburger rides as well as high-speed drills that combine all these skills into a nonstop, heart-pumping workout.
