I train twice a day upwards of five times a week.I do both cardio and weight training,my main interest is in weights.I know that muscle weighs more than fat and I expect to be heavy.I do find it very hard though to control my weight,with a good diet and the amount of training I do,could there be an underlying problem that is stopping me from shedding the fat and excess weight I have.I have lots of energy,dont tend to get run down easily and feel generally fine.I have also tried taking ephedrine this seems to help lose weight but im still struggling.
