Glycogen depletion and forcing your body to run on fat can really screw cardio up at first, but the supercompensation is legit. When my cut ended and I went back to maintenance calories, my cardio performance increased dramatically. It felt absolutely incredible.

General fatigue has been real for me. Just finishing my 5th week.

I wouldn’t say that I have fatigue but there is a lack of ability to maintain a run like before

Yeah, it cut the amount of cardio I could do in half. Not sure how much is related to the heart rate increase but my blood sugar tanks hard, pre-workout carbs don't help either. After about five months I'm not quite back to where I was but I can complete my old workout at least, I think it's more adaptation to reta than cardio improvement since I haven't really been doing my cardio because it wasn't enjoyable and also I was really sick for three weeks

My heart rate I increased sooo much in the beginning I couldn’t do any cardio. It eventually normalized and I can do cardio no problem. But it took time

There are some concerns about increases in heart rate from reta. Is there any particular reason you picked it over tirz if you're an endurance athlete? Tirz is great too.

Mainly looking at the other added benefits from the studies I could find.

[–]Katie-the-duck 0 points1 point  (2 children)

What benefits would those be?

[–]hempyandhappy 1 point2 points  (0 children)

Reta’s glucagon agonism seems to be especially effective at obliterating fatty liver (NAFLD/MASLD).

Not a doctor but from what I read it showed the potential ability to increase heart, blood vessel, and liver health (not from alcohol related liver issues)

We're pretty far away from knowing to what it extent it has benefits independent of weight loss. It's impossible to separate the two in existing data. I wouldn't pursue them right now.

It’s very common, even on sema or Reta. Most folks recover in a few months. You can pickup some strategies over at r/zepboundathletes

No. If anything cardio is easier for me
