I try to work out in the afternoon, but I just can’t—my body fights me the whole time. But when I work out in the morning, I feel tired for the rest of the day. What is this curse?!
I’m guessing I should just work out in the morning until I build enough stamina so I don’t feel drained afterward. In the morning, I’m full of energy at the start, but then I feel completely beaten after the workout. Does anybody else go through this?


Start slow and build up. 15 minutes of elevated heart rate is a good starting point. Don’t kill yourself when your starting out, you’ll either burn out or injure yourself.
Rest days are important, this is when your body rebuilds and gets stronger whether that is your heart and lungs for cardio or other muscle groups for weight training.
If your baseline exercise is zero it might take longer than you want to build up your stamina to where you don’t feel exhausted all day. BUT it will get there.
Motivation is not reliable DO NOT rely on this to keep you going. Determination is the key to consistently exercising. If you don’t want to do your exercise one day do it anyways. Even if you half ass it. A half assed day is better than a no assed day.
