I just wanted to let you know that I completed your 12 week program and absolutely LOVED it! I am 42 y/o and have been working out for years doing the same old gym workouts. Your program added a new variety and a new found excitement in my approach to working out. I am a firefighter who needs to be in overall physical shape with both cardio and physical strength as heart attacks are the number one killer in our profession. The workouts are 30 to 40 minutes of intense strength and cardio which is perfect for my job . As a firefighter we go from rest to full on intense work which you have us doing daily for 12 straight weeks. I am looking forward to starting the 12 weeks again but adding the TNT workouts each week. I am including some before and after photos which you can see has changed my physical appearance. What you cant see is the endurance that Ive gained. Thank you again and keep the great YouTube videos coming.
