| When the weather isn't nice or its night time I love my treadmill. Heck even when it is nice out I will use it lol but do prefer to run outside. Lately I haven't been doing much exercise so I will just run a mile as fast as I can and stop. Like most state though, I think time is more important. The longer you can maintain an elevated heart rate I believe is much better for you then 'bursting' for distance.
Treadmills are awesome.
What kind do you guys/gals have? How would you rate it? I have a pacemaster gold (non fold up - they didn't have fold ups by PM when i bought it about 1.5 years ago). The quality has been superb (knock on wood). |
