How long does he rest between sets? If he doesnt like running have him get on the bike or rowing is also good cardio. Bottom line eating twice a day is not only bad for you but if your not eating elephant size portions you will never have the energy. When doing cardio the first 15 to 20 minutes is what I like to call down time. Not only do you not start to burn calories you also do not build lung volume in your first 15 to 20 minutes. The lungs are like muscles to and will begin to get stronger as you do. 15 to 20 minute warm up then hit it hard for 5 minutes break for 1.30 minutes then hit it hard for 7.30 minutes then break for 2.oo then hit hard for 10 minutes then break or be done. Just like reps u can build lung capacity witch will help you control your breathing witch will improve stamina. When I boxed I knew how much time I had to get ready b4 a fight. I did all my cardio in incriments to build my stamina. Your buddy has to eat and stay hydrated all the time. He must not be cycling if hes not eating at least 5 to 7 meals a day. I litterally get sick if I dont eat. Protein and carbs gold keys to energy and stamina...Good luck bro, MAC
