i want to exercise more! i have a lot of time on my hands for now, and i'm determined to get into shape (i've never really been in good shape before). i'm eating all the right foods (cottage cheese, protein, fruits & vegetables, lots of water) and avoiding the wrong foods (basically anything high in sugar or fat, very limited on bread and starches). i used to walk about 3 miles in hills a day (with the occasional yoga and cardio kickboxing class), but now i jog about 15 minutes around my local 8 acre park (not sure how long the trail is), then i do it again but do all the exercises they have (sit ups, push ups, other stuff) - basically, about a 40 minute workout. i get a great sweat going, and i'm tired but not wheezing, but a couple hours later i want to do it all over again. the only thing that's really stopping me is that my knees tend to hurt at the end of the run. how much exercise a day will i benefit from? and is it in my best interest to exercise every day? i've heard that i should take a break every 3 days, but man, i wanna lose this weight now. suggestions?
