Though I am enjoying the one-month gym membership my sister gave me as a gift, I'm not sure it is really me.
First, being outside year-round helps my mental attitude. Sun in the winter, or a walk in fluffy or crunchy snow are fun! Walking outside helps to keep me from getting depressed.
The nice thing about the gym is it doesn't matter how cold it is, I can still get in some major miles. Plus, I love the fact I can work on form next to a mirror. It is so much easier to feel walking smooth and not bouncing while on a treadmill, though I am having a hard time pushing off with my toes.
It is really difficult to do major miles on a treadmill. Even though I did only 35 min today, and I even did intervals to break up the monotony, it was still hard to finish. I just get bored too easily.
I really like the weight-lifting equipment. At the same time, we have a bunch of free weights at home and I can probably work up a good routine there.
So, I can see the benefit of gym membership, and I am enjoying it. I just don't think it is something I would be able to keep up because of boredom.
Today I walked for about 40 min total -- 5 min as warmup before weightlifting, then 35 min after. I used the first 5 min as warmup, then alternated a 1-min sprint at a 12-min-mile pace with 3 min at a 15-min-mile. I ended up walking 2.33 miles. My peak heart rate was 173, average heart rate was 133. The treadmill said I burned about 200 calories.
