Xert for ConnectIQ

A full-featured app that displays your current workout information in an easy-to-follow display.  Your target power, MPA, cadence, heart rate and timers are shown and the software controls your smart trainer, adjusting target power and/or interval duration in real-time using the advanced smart interval algorithms.

Displays MPA, the maximal power you have second-by-second. In addition, power is displayed beside MPA and is colour-coded to provide feedback on how close you are to achieving a new fitness breakthrough by exceeding MPA. The app rewards you with a performance medal when a fitness breakthrough is achieved.

Displays fat and carbohydrate usage, colour-coded to indicate when rates are maximal.

Displays how much time you have before reaching your limit as well as how much time before you are recovered, both based on a configurable wattage.

Displays Focus, which is unique Xert derived measurement.  It a time measure that indicates the area of your fitness that is currently being exercised during the current activity.   Strain is a measurement of the difficulty of the activity. It is shown either as a Total Strain value in kJ, which is a sum total of the strain of the current activity or as a Strain Rate in watts showing the current degree of strain you are producing.

Using your Xert™ Fitness Signature, real-time Xert Strain Score (XSS) and Xert Equivalent Power (XEP) are calculated and displayed. Configure the app to show the data for the entire activity or for your current lap.

Optimizes your cadence by displaying a gauge. The gauge slides up when you’re pedalling too fast and slides down when you’re pedalling too slow, relative to Bioshift’s determined optimal cadence for a given power output.

What People Are Saying

“The adaptation from exercise is not about the total number of watts you produce, but where and how you place stress on the body. Integrating effort prescription with a fitness signature is sheer brilliance and is going to become the future of training.”

Michael Freiberg, World Omnium Champion and Founder of Terrain Dynamics, makers of the AirHUB

“Xert’s ability to pinpoint the specific intensities that make the greatest impact for each athlete, sets it apart from all other training software programs.  No matter what level you are at, Xert will have you at your best.”

Steve Neal, Cycling Coach - The Cycling Gym

“I love it so much that I have begun to implement it with clients at my studio and online. Anyone with a current-generation Garmin or Android App can run the program, witness the workout in real-time, and challenge themselves mentally and physically to regular fitness breakthroughs. As a full-time coach since 1993, I really have never seen anything like this at all, and I can’t wait to see what’s next!”

Richard Wharton, USA Cycling Certified Coach - Cycling Center Dallas

“The idea of MPA modelling can really change the way we monitor training, both in its post-ride analysis but also potentially real-time monitoring. Using MPA real-time can really enhance how we monitor the optimal doses of work and recovery during interval workouts, making training maximally efficient.”

Stephen Cheung, Ph.D., Professor, Sport Science Editor for www.pezcyclingnews.com, and co-author of Cutting-Edge Cycling
