Coach MK uses a heart rate monitor every time she runs, and the coaching rule she is known for is the 140 cap. 140 is a cap (not a target!) on all easy effort runs. As long as you were below that effort level she will totally buy that the run was easy effort. The higher you were above that figure, the less likely it is that your body agrees that your run was truly easy. (Please note: Coach MK isn't going to kick you out if you break this rule, but she isn't going to argue with you when you insist that your 90-minute run with the average heart rate of 172 was sooooo totally easy, either.)


Watch this video to learn more about the suites of products we plan to build out over the course of 2019 and 2020:


NOTE: most products are in beta mode; please click the link below to be added to the mailing list to be notified with additional suites of products are launched!


We are building out three suites of products: 


Runner, Interrupted™️: a suite of support products that cater to runners whose journey is currently, temporarily, derailed by injury. 

Beta testing expected to launch in 3Q19


(Re)Build: A suite of support and fitness products that cater to folks who are new to fitness as well as folks who are returning to fitness after an extended break (6 months or more) for any reason (injury, pregnancy, surgery, illness, LIFE). We never judge. All are welcome, there's a place for everyone in here. We aim to get you ready to move into the Maintain suite of programs in an expedient manner.


Maintain: A suite of coach-led fitness products designed to protect a level of fitness gained over the course of a training cycle or developed over a longer period of time. This suite of products aim to maximize your cardiovascular health and meet the American Heart Association guidelines, the very guidelines that kept Coach MK's father alive 35 years after a quintuple bypass. As a bonus: we maintain the elements of most training plans so your transition from maintenance to performance for a half distance or longer will be seamless (read: you will only need 10 weeks to ramp up for a marathon).
