Apple's planning to release WatchOS 4 to Apple Watch wearers in the near future, and up until now, we haven't heard much about how workouts will change. Today, however, iHelp BR says it's discovered a host of new icons that it thinks indicate support for a wider variety of workouts.

The icons depict the following activities: badminton, barre, baseball, step training, surfing, sailing, skating, snow sports, pilates, paddle sports, kickboxing, jump rope, lacrosse, stretching, functional strength training, golf, fishing, fencing, equestrian sports, downhill skiing, dance, curling, cross training, cricket, cross-country skiing, core training, bowling, boxing, and climbing.
