My workout isn't working out. What am I doing wrong?
So, based on this question
I've been going to my gym about three or four times a week and walking on the track. I tried the treadmill and the elliptic but the treadmill was boring and the elliptic hurt too much so I stopped both and stuck to the track.
On the days I don't walk at the gym I stretch at home. I replaced my chair with an exercise ball and use that most of the time I'm home, and I use it to exercise with as well. It's great for my back! I also don't have a car so I walk everywhere, even to the grocery store that's two miles away.
Here's the thing. I'm not getting any fitter. When I walk in the gym I walk fast enough to break a sweat for a good twenty to thirty minutes - five to ten minutes to warm up and five to ten minutes to cool down. It all depends on how I feel that day. I started at thirty but worked my way up to about forty five minutes. I guess I'm no longer the slowest person on the track but I'm still way slow. I still get wheezy walking up the inclines scattered around the campus and I'm almost certain I haven't lost any weight -- since weight-loss isn't my goal I haven't really checked, but my clothes still fit as they did in October.
So, what am I doing wrong? My knees and legs hurt after forty-five minutes of walking on the track so I don't want to push it to an hour, and I still have to walk home after the workout - another ten to fifteen minutes. I cannot run, it would do me serious damage. It's been nearly six months! I should be seeing some kind of results. I'm getting kind of discouraged here.
Any advice? Hints? Suggestions? I'm open.
