sir good morning... what can you recommend? i'm 31 yrs old and 135kg (morbid obese)... i want to lose weight at the same time not have any saggy skin.. i'm going to the gym now and i just lost 4kg in a week... the trainers there wanted me to do body weights and more cardio but i think lifting weights is better... they are also telling me to take some supplements but they are too many and i don't know what's good for me.. hope to hear a positive feedback from you guys. thanks!
