@countrygurl32 It’s great that you’re working out to improve your health, but it’s important to remember that being healthy doesn’t necessarily mean having a smaller body. Growing muscle is healthy too. In certain circumstances, gaining some fat can even be healthy. It all depends on context.
I can see how a certain level of muscularity could make practicing yoga more difficult, but it seems like that would apply more to someone with a competitive bodybuilding physique, not just someone who puts on muscle and keeps up with their yoga practice. I don’t think he does yoga, but jujimufu is an example of someone who’s pretty huge and is also incredibly flexible and mobile. For every anecdote, there’s a counter example.
You’ll only get “too heavy” for inversions and balancing if your strength doesn’t keep pace with your weight.
With protein, it’s more important to prioritize your daily allotment. You only take creatine once a day if you choose to take it at all.
Doing more yoga is probably the best way to train for yoga, but you can supplement your yoga practice by focusing on strength in specific areas. So if you want to strengthen your back, work on pull ups, pull downs, rows, etc.
