Forgive my ignorance but I'm keen to hear your opinions on my situation. I'm a tall slim build, 6'3" and weigh in at 93 kg. I maintain a fairly regular exercise regime in the gym working all muscle groups with the aim of maintaining good general fitness and perhaps make it to 95 plus kg with muscle mass and low body fat. The issue is I hit the wall some days about 45 mins through my workout, especially if it's a leg/ lower body day,now, if I have a sugar hit it gets me going and all is good,but hey it's not ideal. I usually work out later in the afternoon and always eat a good lunch about 4 hours before working out. I have one or two coffees a day. There are pre workout supplements which I assume are caffeine,energy drinks etc etc. just curious to hear anyone's thoughts on this?
