My name is Holly Del Rosso, and I'm at The Works Personal Training Studio in New York City. And this is fastest workouts on a treadmill to lose weight fast. With these exercises, you're going to burn the most calories in the shortest amount of time, trimming your waist and giving you overall heightened athletic performance. This exercise routine is for beginner to intermediate fitness levels. You're going to have your treadmill inclined at a four point 0 and the speed is at a one point three. You're going to drop down to a lunge, back knee down, couple inches off the ground, chest up, face looking straight ahead of you. We're going to stay here for 30 seconds. After 30 seconds, you're going to bring the speed up to four point five miles an hour. Make sure that your abs are engaged the entire time. Jog it out for 30 seconds and then, bring it right back down, back into your lunges. Thirty seconds right here, and after 30 seconds of your lunges, come right back up. You're going to repeat this entire routine, until you get to five minutes of training. Once you get to five minutes, you're going to go into a basic jog, five point five miles an hour. And then, you're going to repeat this. The more height you get in your heart rate, the more calories you're going to burn in a shorter amount of time.
