Its summer and i want to lose weight for the upcoming school year in 2 months. I am training 4 days a week in boxing for 2 hours each time and run on the other 2 days. I am starting to eat very healthy and am doing situps and all that. How much weight can i drop in 2 months? I am 6 feet 1 and 180 but have alot of fat and am uncomfortable changing in front of others. Also how long would it take before my stomach was hard and you could see my abs? Thanks alot
