Testimonial by Fitdigits User Greg R.

I have been using Fitdigits for quite some time, and my iPhone has a record of 369 workouts. I use it to sync with both a MIO Alpha wrist heart rate monitor and a Polar H7 chest strap HRM. The primary use is to log P90X type workouts and I have been through the original P90X, five times; P90X3 once and am currently in the second phase of P90X2 for the second time. I also use it to log workouts at the gym on a treadmill or an elliptical.

Heart rate monitoring is a great motivator for me. For example yesterday I did the 30-minute kick boxing routine from P90X3 called MMX. It is intense; a 30-minute HIIT workout. Today’s workout was the original kick boxing routine from P90X called KenpoX. Attached are the heart rate graphs for the two. You can clearly see how the MMX is more intense, but KenpoX is almost an hour and burns more calories. (Comparison was 400 cal. vs. 565 cal.)

MMX Workout. 400 Calories

KenpoX Workout. 565 Calories

What else can I say but thanks Fitdigits! I¹ll be 60 years old in February. Fitdigits is helping me to maintain my fitness and health, which are two very important aspects of life. I was able to run in a Warrior Dash in August with my two sons no doubt because of my commitment to fitness and Fitdigits has been a big help in keeping me on track.
