Cardio exercise and Reta

I've gained some strength. Cardio feels about the same except my heart-rate numbers run higher on retatrutide. I'm also doing less cardio overall because I'm trying to keep muscle.

I don't have anything useful to add but I'm also curious to hear what others have experienced with those same questions.

No exercise for me. The heart-rate thing is interesting though, the stuff I've read about reta mentions it. My usual reading is 72-76 when I'm just sitting after walking back from the kitchen or similar. At a recent doctor visit it was 76. I got a new Sleep Number bed that tracks heart rate and it showed 64 while sleeping. I've been on reta eight weeks now.

I ride about 12 miles each way to work. Honestly it doesn't feel any different, but I've dropped 20 pounds so carrying less weight makes the ride easier.

I should get a health tracker. Sometimes I don't really want to know though, which is probably not the best mindset. Good info, thanks.

I do 25 minutes of fasted zone-2 cardio five days a week on the treadmill at 3 mph with a solid incline.

Cyclist and triathlete here. It depends on intensity. True zone-2 efforts don't feel that different except it's harder to stay in the lower end because of the baseline elevation. Harder sustained efforts or intervals are where it shows up more. I feel a bit limited at the top end, like my tank empties faster, though it's not dramatic. Not related to heart rate, but in hot weather I have trouble getting enough fuel and fluid in without hitting nausea because of the fullness feeling. Hope that makes sense.

I just started reta and the morning after dosing I went to the gym as usual and got light-headed with a fast heart rate on the treadmill. I've switched to taking the dose on my rest days instead.

The raised heart rate is one reason I'm still deciding whether to switch from tirz to reta. I'm a runner doing 40-60 km a week focused on 5k and 10k. I notice an upper limit when pushing hard and sometimes some nausea during hard efforts the days after an injection, though that's not from the heart rate. My heart rate came down after a few months but is still 5-10 bpm higher than before. Curious how reta compares to tirz on that.

I'm having a bit of a struggle in the gym. Random waves of nausea hit and the same weights feel harder. Could just be the calorie deficit and weight loss. Started reta about four and a half months ago and I'm at 3.5 mg.

I've exercised my whole life. Now in my late 60s I do about 30 minutes of resistance work three times a week and walk 6-8 miles every day. During six weeks on reta I didn't notice any change in my numbers or how exercise felt. I'm now trying tirz and so far it's the same.

I've been on reta about five weeks and lost around 12 pounds. No noticeable weakness in lifting even though I go five days a week. Strength is holding steady and no change in heart rate during my usual 30 minutes of cardio. On wegovy I did lose strength, so this is different.

Reta has definitely changed my workouts. On tirz alone I could usually find the energy to hit the gym and reach my lifting targets. Since adding reta back in January I've struggled with several lifts that used to be fine. I'm trying to carb up beforehand but it doesn't seem to help much. Interesting how individual the responses are. I'll finish the reta plus tirz experiment at the end of the month and see if lifts return to normal once reta is out of my system. I know the thread is about cardio but lifting is basically my main cardio.

I feel like my heart rate is higher than usual. Strength is about the same but stamina feels lower. Not sure if it's just from the big calorie cut.

I didn't notice much difference myself. I do six-week cycles of cardarine though, and that definitely improves my cardio within three days. I stick to 10 mg a day and don't run it longer than six weeks because of the earlier studies.

Cardio has felt pretty much the same. My Apple Watch hasn't shown a higher resting heart rate. I do feel like I have a bit more stamina lately, though that might be from working on running form and getting new beginner shoes I really like.

New to reta, fit 59-year-old male in week six. I notice the heart-rate increase but not in a bad way, more like the motor is revved a little. No noticeable change in athletic performance either way. I just feel like the reta is active, if that makes sense, like something else is onboard doing things that all seem positive right now.

I'm 46, lift three days a week and box most days. Boxing felt hard at first when I started reta, probably because calories dropped sharply. Now at six months in there's no effect on boxing. My cardio has actually improved because I'm not carrying the extra weight anymore.

About five days before starting reta my non-fasted glucose at the doctor was 73. The first week on reta I had symptoms that felt like low blood sugar. I'd eat some quick carbs like a banana or oatmeal and feel better. It happened two or three times. Once I stopped going so low-carb the symptoms went away.

Good post and useful to read people's results. I'm interested in this too. I was at the gym two or three times a week plus a couple runs. Now training for a half marathon in two weeks, after that I'll probably shift back to gym focus but keep some running because of another trail half in September. Really don't want to see running performance drop, but I was only planning a short-term quick cut to get a bit leaner anyway. Curious if that plan sounds reasonable based on what others have seen.
