I’ve done yoga on and off since 2011 (and recently haven’t been able to go because I have a 4 month old son). I very much like it, and think it has great benefits for lifters and other athletes. Really wish I could still make it to a class every week. A few things to be advised of if you are looking for a class to try:
There are many different types of yoga: I did/do mostly hot yoga in the “Bikram” style, a specific class that does the same sequence of 26 postures over 90 minutes in a hot room. I like this a lot for lifters because there’s a lot of emphasis on spinal health, a good dose of balance work, and little weight-bearing stuff that would be hard on wrists or shoulders.
There are also “hot flow” classes, “vinyasa” classes (think downward facing dog), “yin” yoga (prettt gentle, sit and hold postures for a reallllllly long time), and gentle/restorative yoga (mostly just sitting or lying on a mat and breathing).
Many yoga studios offer some sort of intro special (ie 7 dollars for 7 days unlimited, 29 dollars for unlimited yoga for your first month, etc). If you find a studio with one of those, take advantage and go multiple times. It’s really hard to judge how much you’ll like yoga from just one class. Could be a bad instructor, could just feel overwhelming trying to keep up the first time. Gotta go to at least two or three classes to give it a fair shake.
As with anything, yoga instructors can be quite variable in quality. Some are very good, understand that their students all have different goals, and will work with you to offer modifications or special cues to accommodate where your body is at. Others are just yoga snobs who look down on lifters or runners or anyone that isn’t yoga-first. So try a couple different classes and hopefully you find someone that seems to get that a strongman or powerlifter is there as a adjunct to their primary sport and will work with you to make the yoga practice work for your goals.
Finally, some big box gyms offer yoga classes. I would advise against taking those. My wife is a yoga instructor and has periodically taught at gyms, always hating it (whereas she likes teaching at dedicated yoga studios). It’s too loud, classes usually aren’t full (meaning you don’t have many good examples to work from if you’re a new person) and they just feel like second class citizens in a gym (ie many gyms like to show that they have a million different classes as a tool to sell memberships to people, but they don’t actually give a shit about the classes).
