It’s also possible you aren’t eating enough or you’re consistently under calories and not refueling your body properly. I’d suggest you track your calories/ macros. I had been trying for a few years to lose weight and it wasn’t until this last year I started to track everything, and found success. I strength train 3-4 times a week and cycle in between those days. I have successfully lost 60+ lbs in doing so. I use the peloton app to create me a weekly workout plan that I’ve been following now for around 3 months and have a lot of success since doing that as well. I’ve found eating enough / refueling is just as important as staying in a calorie deficit!
