I've been trying to lose weight for the past four months. I currently weigh 275 pounds and am 6'2". My top weight was 290 a year ago. I'm not having much luck recently, I've been stuck between 275-280 for two months now. I feel - at my weight - I should be losing more, faster. I cycle 3-4 miles a day, and play tennis for about two hours a day 5 days a week. I don't eat junk food, and guessing my calorie intake, it's around 2'500 calories a day. I LOATHE lifting weights but love plyometrics and I do these 3-4 times a week. I won't go swimming because of my weight. Can someone offer advice? Thanks.
