Friends, I signed up for the gym to lose weight. Height is 176 kilos, now 88. The teacher said come to the gym on an empty stomach for cardio, then we will do weights. If I go in the morning on an empty stomach, if I eat my food after doing cardio, will it be more efficient if I rest for 2 hours and go for weights, or should I do weight training on an empty stomach directly after cardio?
