Hello. I'm a 16 year old male and i want to loose weight and gain some muscle. I am 6ft 1inch tall and weigh 277lbs. i use an application on my phone that determined that i should have about 1950 calories per day but i reduced that to 1900. i have been sticking to this for about 2 weeks and according to my weighing scales i have been gaining 1lb per week. I used to eat about 3000-4000 calories per day so i think i should be loosing weigh right? also i weighted myself with no clothes one week and weighed 277 one week, 276 the next and 275 the next while i was going up 1lb per week. i also wore the same clothes when weighing myself so i think my scales is broken. my mom just got a new one but i have yet to weigh myself. my goal is 1.5-2lbs per week. i have very little time to exercise, the reason being 2-5hours of homework every night. i get about 1 hour of walking at the weekend spread out over friday, saturday and sunday. i sweat a lot and continue to push myself and not give up. what im asking is, are there any good exercises or exercise machines that might be good. i dont want any gimmicky junk from any advertising tv channels unless they work. i have dumbbells and was thinking of getting a rowing machine or an elliptical machine. also i eat pretty healthy compared to the way i ate before. thanks for any advice and support
