Hello Ive been dieting for a while to try to lose those last few stubborn pounds but im having trouble now keeping up my workouts cuz of energy. I do cardio 5 days a week and lift 3 (split routine) I burn a lot of calories because Im afast runner normally about 1500 per cardio session plus im also an aerobics instructor but thats included in the 5 days cardio. I did the 500cals under mantenance for a while which for me is 3000 calories a day and got great results but that stopped about a month ago so I tried adding an extra day of cardio but for two weeks nothing happened then the next week i tried cutting calories a bit so I went down to 2700cals a day and I did get some results the problem is when I cut the cals down it didnt have enough energy to even workout and I was always lethargic and tired even if I got enough sleep. So I dont know what to do? I dont measure bodyfat often I normally go on how my clothes feel I can tell by my workout shirts because there alot tighter. weights not an issue cuz im 185 and 6ft 21 year old male.
