I don't mean this metaphorically. I'm actually making the leap to try and start a new class next month, and leaving a 20 year accounting career to start a yoga business was one of the biggest jumps of my life.
My husband and I recently joined a gym where you go from one station to another for strength and cardio training. Periodically they have us jump up on a big box, ranging from 12 to 24 inches high, and I pick the lowest one I can.
I can't do it at all. I look at it, imagine what it takes, then . . . freeze. I can jump up a few inches from standing in place. I can step up on the 12" box one leg at a time, and I can leap over a very low 6" hurdle (although my knees don't like it).
I don't know when this happened in my life. I'm not sure I ever could jump up on a box, but I think it's the fear that's stopping me because I keep seeing a face-plant coming! (I just tested it and made it up on a 4" dog cushion - yay!).
Although it was embarrassing in class, what got me through the fear and the workout is remembering what I tell my students: Don't focus on what you CAN'T do as much as what you CAN. In the grand scheme of things, not being able to jump up on a big box isn't such a big deal.
If you want to practice yoga with me (with no jumping!), I provide many options, includinggroup classes or 1-on-1 sessions via Zoom or in-person, and video recordings.
