Kettlebell - Figure 8 Lunge

KB Lunges can also be done a couple of ways. Some prefer a Walking Lunge where you actually walk and weave the KB between your legs. Others prefer the stationary Rear Step Figure 8 Lunge, where you weave the KB as you take a step back with each alternating legs. Each variation targets the same general musculature. 

If the hand-off (or weave, or pass-through) is too complicated, then hug the KB as in the Single KB Front Squat and do lunges. Start with what feels most comfortable and balanced, then alter between each of the methods.
