5 years powerlifting, 5 years wrestling, 3 years BJJ, 2 years dancing (normally don’t count that, but for Beat Saber I guess it’s relevant?), and a spattering of other sports like climbing/hiking for shorter time periods. Have helped a small handful of friends get fit, the biggest success story dropping 100lbs and now being pretty decent at BJJ where he initially couldn’t walk over half a mile without a long rest.
Little formal training but I enjoy reading about the theory. I don’t have any particularly compelling example to give here. Just lots of books/articles/diagrams/studies/self-experiments spread out over that time. For an example of the kinda person I read look up any study review by Greg Nuckols.
The comments on safety I have a high amount of confidence in. They’re all things that follow directly from knowledge of anatomy. Tennis existing is convenient because it’s always nice to have a real world example to verify what the theory would predict.
The rest is half anecdotal half me trying to think about how similar-but-different studies I’ve read in the past could apply. Studies I thought about before replying were 1) even walks are enough to improve mortality 2) any study with short workouts with no long term progression plan show only minor body improvements 3) rotator cuff injuries are both surprisingly common and surprisingly benign 4) crossfit injury statistics are relevant since you’ll be going for speed and be fatigued at the end. Anecdotes I thought about include 1) my DDR playing friends certainly don’t go hard enough to match real cardio training, but they do more than just walks 2) I know a dozen tennis players, only one got tennis elbow, and it went away in a few weeks 3) Even people who do the Charleston all night don’t get biker-tier legs 4) Napkin math is enough to see this won’t be great for fat loss without diet changes
Also, there are health reasons to care about the muscle/fat stuff and not just cardio. Muscle mass has been linked pretty well to a reduced risk of alzheimer’s. Obesity has been shown to still increase mortality even controlling for cardiovascular ability.
The 80-20 rule applies though. Find a sport/activity you like (weighted Beat Saber counts imo), control your calorie input, and get a good variety of nutrients and you’ll be fine. If you have any reason to believe you’re in a risk group and need more I can help point you towards the right resources to read to evaluate that.
