walking is a cheap easy way to start. i started walking moderately (just fast enough to make me breathe harder) for 30 minutes. when that became easy for me, i stepped it up a notch and tried walking farther (i started at a mile, then tried for 1.25 miles in the same time and slowly increased it). when THAT became easy, I tried walk away the pounds, which is a video that incorporated knee lifts and arm movements along with walking.
when THAT got to be too easy, i tried jogging. thats where i am now, lol. the first time i jogged on the treadmill, i lasted about 12 secs and it took me 4 minutes to recover...today i jogged/sped walked on the treadmill and i hit a mile after 16 mins. about 6 mins of that was jogging. i am SUPER proud of myself for that one!
I am working my way up to 12 min or less per mile. after that, im not sure where I will go. I also do circuit training (a bunch of different exercises in a circuit) and weight lifting with friends from work.
i start with small goals (try a 10lb weight instead of the 5 i used last week) and i increase them.
Ive still got about 115 lbs to lose, but I am more fit than i was 20lbs ago. I can actually jog, when climbing stairs used to give me asthma attacks (i dont have asthma)
start where you need to, but dont stay there. always challenge yourself and push yourself PAST your limit, a little at a time
