Strained groin substitutes and rehab exercises

So, not surprised given my luck, but I tweaked my groin last week during squats. It’s infuriating as I was finally making some of the best, consistent progress I’d made on squats in my life, but o well

Now I’m trying to figure out the best options for rehab and for trying to continue to make progress, as much as possible, while I get back to 100%

For the rehab exercises, is it just lots of good girl bad girl exercises? Anything else really good for groin work? I read something that focusing on core engagement during squats is the best way to protect your groins. Anything else for reducing injury risk going forwards?

For substitutes, would you just do lots of isolation leg stuff? I’ve been doing PPS with everyone and been loving it. I can’t imagine any sort of iso lift will replicate squats or deads, but it’s better than nothing. I can kind of do deadlifts, but I feel like it may be teaching me bad form to do them by staying very narrow and taking my groin out of it

Thoughts?
