Ischemic Preconditioning

By Adam Mills | March 26, 2012

One interesting aspect of studying exercise physiology is the ability to incorporate a multi-discipline approach to developing new ideas. The major underlying theme is the body being placed under a form of stress and monitoring the response. The crossover between exercise science and medical research is well founded as it’s not uncommon to see researchers…

Early Season Stages of Grief

By Adam Mills | February 1, 2012

Denial–  I’m fit.  I’m just having a bad day. Anger–  I’m so mad I let myself get so unfit. I’m getting fit now!  These guys are a-holes for showing me I’m unfit. Bargaining–  If I get through this, I’m going to start training 30 hours a week so I’m never unfit again. Depression–  I’m so…

Sometimes it takes an event that can described as nothing except sorrowful to give you a bold reminder of your mortality.…

"My work/life balance has not always allowed me to train/race or even ride as much as I would like. I appreciate my coach for his willingness to adapt to my challenging schedule so that I am able to enjoy my limited time on the bike without feeling guilty or frustrated for having a lack of fitness. Adam and Source Endurance have been a great partner for the past 10 years both on and off the bike!" 

- Patrick Robinson

“My season goal was to finish DK200.  Goal crushed.  I can’t say enough how well the plan leading up to Dirty Kanza worked out.  Perfect on so many levels, I was beyond ready mentally and physically, evidence by beating my DK goal by almost 2hrs.  BWR challenged me technically, but the rest was a piece of cake in terms of my readiness for the duration and heat.”

– Sonja Johnson

“I’ve loved working with Grant and Source Endurance so far, really happy wtih the results I’ve been seeing this cross season!”

– Alex Edwards

“Just wanted to say the year is turning out okay despite rocky winter. Steady build has me seeing power numbers as high as I’ve seen in a decade. Now onward to DK 200. Thanks for the guidance!”

-Trey Harrison

“Basically just writing to say a big thank you.  I truly don’t think my performance would be where I’m at without the training regimen you provided. During those primes and sprints I felt unstoppable.  I was calculated, composed and even more importantly, coached, on exactly what I needed to do.”
