Hey, figured I'd post my progress as I attempt to touch the floor. I've been training for 4-5 years and although I'm sure my flexibility has improved I can't actually say I'm any closer to the floor. After reading http://www.martialartsplanet.com/forums/showthread.php?t=96381, I figured I'd give it a try. I started at level 1, as I don't have great leg strength and a 20 year old knee injury that bothers me from time to time. Only 2 weeks in so far and have progressed to level 5 doing 3-4 workouts per week. I decided to stick with level 5 for at least 4-6 reps to help prepare me for the increased time of tension and hopefully remove the need of a chair for assistance. Everything is going good so far, having a bit soreness (the good kind) overnight, but nothing that last more than 12hrs past workouts. Got a couple guys doing this with me after class, hopefully we can keep each other accountable. Probably should get a measurement for progress tracking, but I guess I'll know when I reach the floor.
