Sun salutations are an easy, flowing set of poses that stretch a lot of your body. I didn't really take classes but had an opportunity for a couple months to do yoga with an instructor in a group setting and our group had every body type. If someone struggled with a particular pose, there's either a way to modify it or try something similar

The sessions were great. Sometimes I was able to push myself physically, but they weren't geared for that; just chill beginner yoga. I certainly did see progress in myself though, and was bummed when they ended
