Here is a great exercise with tons of application for our sport. Single leg partner lifts are a great total body exercise that can be done both during practice sessions and while working out.
It is important to remember to get you hips up under you prior to starting the lift to prevent staining your lower back.You can start by working out with a lighter partner and working your way up as your strength grows. In this video my partner is weighing in at 235lbs. You can do this for reps or as part of your single leg training for finishes.
You will see after the video clip an example of where this lift comes in handy. Too many time as a coach I see wrestlers/grapplers who cannot finish a takedown due to not having the strength to lift their opponents
