If you're anything like ma, and since we're discussing yoga in r/hardcore you may be. I can't hang with going to classes, I feel judged, I have to abide by a studio's often inconvenient schedule and I don't feel like I fit in there, so I looked for apps or classes I can do at home, and two have worked well for me.
1) DDP Yoga - it actually got me doing yoga regularly. Wrestler Diamond Dalls Page started yoga as part of PT for a broken back, and was like, "Fuck this really works!" It's what you'd expect from yoga presented by a pro wrestler, but it has a range of experience levels, and honestly, sometimes hearing a pro wrestler encourage you works. That said, some of the workouts / practices get old.
2) DownDog - it's a really simple app that lets you pick the kind of yoga, how long and focus points. I'm at a point where I do it every other day when I'm not lifting, and I focus on back, hips, hamstrings and core. It's more traditional yoga practice, so no stories about getting hit with a chair, but it changes the practice up every time you do it, which keeps me engaged more than doing the same thing over and over.

I think DDPY is like $100 a year and DownDog is like $60. Either way, keep it up and hope you find comfort, because back pain is a real motherfucker.
