Walking Lunge (with jump)

Step out with one foot long enough to achieve 90 degree angles in both knees as you drop into the lunge. From here, jump straight up in the air as high as you can. Land in a ready stance with feet hip width and setup for the next rep. I think it helps the form to have people lean back slightly as they step out - this tends to help clients finish with their chest up as they drop into the lunge instead of leaning forward.
