'Jason, thanks for the email information you send out periodically. I know I have not signed up for any of your classes, I prefer to workout at home. With a 4 year old and a newborn, it just makes it easier to stick to a workout schedule... I do enjoy reading the information you send out. It is very informative and helpful. I am always looking for new ways to my workouts or nutrition!'

'Hello Jason, I will say first and foremost, I always look forward to these news
letters for the knowledge and expertise you bring and for
your honesty. I am 5' 8", 215 lbs. and back in February I weighed
245 lbs. It was very hard for me to believe at
first when I read that the traditional cardio routines were
not the way to go if I wanted to maximize my weight loss, but you
backed up what you were saying with factual information and
so I believed.. So since then I have been eating right and working
out consistently (interval training with 30 to 60 secs
maximum rest in between sets) and have been fortunate enough to have
lost 30 lbs so far. My goal weight is 190 lbs and so I
have 25 more lbs to go. So thank you for what you are doing!!'

'Since I could not get to any of your classes, I have been reading the email instructions and using some as they fit into my day I have lost 14 pounds 15 inches in total and when I work out I don’t even get out of breath. Protein shakes for breakfast and lunch and sensible dinner treadmill every day except Sat with some kettle bell and dumbbells'
