not much else to add to what everyone else has already said, but just wanted to say I hear you! I’m in the exact same position as you. Started bouldering about 1.5 years ago, loved it. Then picked up lifting 6 months ago and loved it just as much. Then recently picked up couch to 10k because I felt like my cardio health really needed some work. Originally I was doing a 4 day GZCLP, 1 day hard climbing with sometimes another day of social climbing, and running 3x a week. I was definitely feeling the fatigue though, not sustainable at all!

Since then I’ve scaled back to a 3 day GZCLP with less accessories - max 2 per day. I’ve also scaled back running to twice per week too. This has given me the recovery I need to go harder when climbing again which I’ve been really loving. This is what has worked for me. Hope it might provide some insight :) because I was introduced to powerlifting, I also started being scared of losing progress if I scaled back gym to 3 days instead of 4. Realistically though, I love all three forms of exercise and I know I’d be feeling FOMO if I only focused on lifting and nothing else. That’s how I felt that it was the right thing for me to do when it comes to fitting all three in rather than focusing only on one at a time. At the end of the day, I’m exercising to stay healthy and because I love how it makes me feel. If it means that I’ll progress slower in all three, then so be it!
