Ok I had always read that doing Cardio first thing in the morning on an empty stomach is the best.Now i was doing this for a while,and yes I was seeing results.But i just didnt have the energy to really push my self in the morning.Now since I start up work on Mon I've been trying to get my schedule back to working time.So being that I have to leave my house around 600 for work I started doing my Cardio in the evening usually about an hour after a meal.Now one thing I can tell you is that I'm much more pumped up and alive in the evening.I mean I just feel I'm getting much more out of my workout in the evening than I was in the morning.So the point I'm getting at is cardio in the morning is not for everyone if you find it hard to get going in the morning try switchin it up to the evening or late afternoon, the results may better than you think.
