Strangely good for morale after smoking your Soldiers all week long. When we were really going hard during PT after deployment, mine actually started asking me to do yoga every Friday. I didn't object, because I was sore enough by that point in the week that it was good for me, too. I guess we all need a recovery day every now and then, even (or perhaps because?) when our PT scores suck!
The gym closest to us has a yoga class every Thursday for pt, so I've been thinking about doing that with my guys. The thing is though, at Campbell we have sports every Friday already (which I'm not a terribly huge fan of), so most weeks I'm already limited to 4 days maximum of real pt, plus with going out to the field, it's hard to get time to actually improve our fitness
Yeah, our sports on Fri were cancelled by then. But there's all kinds of fun field PT... Log PT, Rifle PT...
I actually led the yoga myself. We had a lot of IT band issues from PRT, so they got some running/PRT specific sequences.
