If loosing fat, cardio can speed up the proces 2 or 3 times faster. I started doing the crosstrainer at home, and the waist size is actually getting 1 cm smaller every other day. When i didnt do cardio, the waistzise went 1 cm down a week. I keep the heart-rate at 140 a minute, to be in the optimal fatburning mode. I still eat sweet's, sugars, whole eggs, fat meat, and im still loosing fat fast. Do cardio my friend. im doing 1 hour a day, now im gona go for 90 minutes of cardio a day.
