Most dance studios have embarrassed the online platform around here, the vast majority seem to have just switched to zoom classes and carried on. That is a lot easier to do with dance than it is in gymnastics.
Dance requires very little equipment. It’s very hard to keep gymnasts engaged through zoom (what are these gyms doing that have the kids training on zoom 5 days a week). Sure we can work strength, fitness, flexibility, conditioning, handstand, basic skills etc. But with no apparatus, and many of the skills the kids are doing, not really being safe to do at ho,e, we are very limited.
