Yeah, what Nametag said. Generally, IME, it takes 1 or 2 weeks to get to the point where you’re not feeling exhausted from your workout if you start out out of shape.
Secondly, you’re doing yard work, which is probably a lot of start and stop, not to mention dirty and not very “organized” as far as a progressive weightlifting routine, or cardio. Meaning, you’re just going out and tackling it hard on from start to finish right?
Most “real” workouts have a warmup period, a hit it hard and steady part, and last a cooldown of sorts.
Do you have music to listen to while you’re doing this? (I can NOT do cardio without decent music, CAN NOT :D).
Next, you’re doing this in the early morning? You may not be a morning person, I know that I don’t feel all that hot after morning workouts, but it’s not the workout’s fault, it’s that I’m not a morning person.
Last, finally in answer to your question, yeah, I usually feel pretty darn good after a workout, I know I’m quite a sick sick girl, but I’m actually disappointed if I don’t get sore from my weight training sessions, and strive for new things all the time so that I’ll hurt (how sick is that? :D).
The fitting into your clothing, and looking great is, I have to admit I’m shallow, is my favorite part. But the feeling healthy and energetic is a good part.
When I first started doing it, I used to have to practically crawl up the stairs out of my gym. And I swear, I spent the first two weeks having a nap nearly every afternoon. And then, one morning, I wasn’t even thinking about it, I realized about halfway out to my car across the huge parking lot (my former gym is in a big mall), that I’d just about flown up those stairs and it not only hadn’t winded me, I’d barely noticed!!
Good for you for your start in fitness and your weight loss! If you keep it up, the “endorphin high” WILL happen, I promise.
