Shin,
I just want to say how great your workouts are. I started in January and each one has been very challenging. I have been working out most of my life and have tried different routines but this one has shown the most results. I'm in my early 40's and these workouts remind me of my days in the Marines. I got bored with my usual routine of the 35 to 40 minute jogs and the isolating weight lifting. I enjoy these because of the intensity and compound exercises. Also I'm not in the gym for an hour at a time.
I have shed body fat and increased my strength (power). I see definition that I haven't had before. I'm in the construction field and it sure helps with my work as I'm doing physical activities all day and makes you feel good also.
Thank you.
