I've never really worked out in life, i'm currently 22yrs & i'm at the heaviest in life it may not sound like much but 140 lbs. I'm really new to this dieting/exercise routine. I had a treadmill downstairs used a lot when i first got it so now i'm trying to get back on track....I joined a spin class last wk which i'm doing for 3 dys and i'll fit in the treadmill on the other dys....my target is 20-25lbs. I already failed today by eating jelly filled donuts. Can someone plz give me a lil advice so i could start getting back on the right track!
