Pretty much the same as the rest of the guys have said. It does indeed take a while to notice changes, and to build muscle. I personaly would highly recomend going to the gym, as it is the best source of exercise, in my opinion. Dont calorie count, again thats just my opinion, just eat a bit less. Cut out choclate, crisps, fizy drinks. Drink water and the occasional glass of orange juice / squash, also milk. Thats the main think to sort your diet out, get ride of those crap just listed. When I do my weights down the gym for maybe 1 hour 30 mins, I find it helps lose alot more calories than doing 30 mins on a rowwer would do. But its all down to you, get into a decent way of losing weight, and doing what exercise you like.
Only do press-ups and sit-ups on its own, are indeed pointless
