I've seen people doing lots of things at the low cable pulley but Planks and Side Planks isn't one of 'em! lol Followed, no less, by the Swiss-Ball Jackknife! (I'll be doing my first Phase 2 Workout B tomorrow night. This ought to be interesting/fun/different/embarrasing. Who knows?!?! I'm getting a little excited!)
When I warm up, I use many of the No-Space Options mostly for ease and flow but also because of the Social Anxiety factor. I'd rather not be traveling 10-20 yards while I'm doing the Butt Kick, for example. lol
And how about those Valslides?
Hardly anyone at my gym carries anything -- maybe a towel and a water bottle. I've started carrying an equipment bag. It holds a bag of chalk, a large band for assisted chin ups, my new Valslides, five pounds of fractional weights, a water bottle, my training log, stopwatch, pen, and iPod. Occasionally I sneak my camera in to take a self-portrait or make a video of magister doing his squats and deadlifts. I bought some towels but haven't worked them into the program yet. Maybe Phase 3.
Life was simpler back the in the Starting Strength days, warm-up included. But it's never a dull moment with NROL!
