Muscular and orthopedic adaptations condition the body to develop a denser blood supply to working muscles and increase the cellular machinery needed to metabolize fat for fuel more efficiently. Changes in bone, muscle, and connective tissue improve tolerance to the orthopedic stress of running, preparing the body for higher intensity training.


Develop a greater tolerance for lactate while increasing aerobic capacity and improving efficiency at faster paces i.e. feel more comfortable while running faster. Separately, strength training focusing on single leg stability and plyometric drills have both been shown to improve running economy.


Anaerobic tolerance: improvements in cardiac output, aerobic capacity and lactate threshold. How much blood can you deliver to the running muscles? And how much of that oxygen that is delivered can convert fuel into energy? Anaerobic power: short, very high intensity efforts aimed at maximizing neuromuscular firing and power output in an effort to improve speed & economy.


Rest is not an avoidance of training but, rather, a critical component of it. Sleep may be the most valuable, most abundant, least expensive and perhaps the most underutilized resource available. Adequate sleep is crucial for proper immune function, tissue healing and can be one of the most productive things a runner can do!


Adequate “good” fat intake fuels workouts, decreases inflammation, reduce soreness and facilitates healing while carbohydrate intake fuels workouts, brain and muscle recovery. Adequate protein intake accelerates muscle growth and speeds recovery by helping rebuild muscle fibers stressed during a run. Effective in-run fueling and hydration bolsters performance.



What I appreciate the most about Gary is that he takes running seriously…but not TOO seriously. Working with him is a great reminder that it’s important to keep a sense of humor and have fun along the way. Training is more enjoyable when you have a coach to laugh with!

Gary has added a level of specificity and analysis to my training that was missing for the past two decades. I know he spends a great deal of time crunching numbers and perfecting the workout plan–something that is way beyond my area of expertise, even as a seasoned runner. I love that my runs are intentionally designed and customized just for me.

He’s also a forever optimist, which comes in handy when the self-doubt starts to creep in. Gary is president of my fan club, for which I am very grateful.

I’ve worked with Gary for several years now and give him very high marks for his investment in clients, his love of running, and his thoughtful approach to training.

Sheyna H., New York, NY

Working with Gary was great! From the very beginning, he set up a program that was challenging but necessary in order for me to achieve my goals. Throughout the process of training he held me accountable while maintaining a positive attitude. When thoughts of doubt crept in, he was right there offering words of encouragement and his faith in my abilities and my training. It all worked! I hit my goals, had a 10 minute PR and qualified for Boston in the 2015 Chicago Marathon. I can’t say enough good things about the whole experience!

Matthew K., Brooklyn, NY

I would not have had the success I did this year if it weren’t for Gary’s help. I set goals for myself and he had the skills and coaching experience to get me there. I cannot thank him enough and I look forward to training for Boston 2020 with him!

Logan G., New York, NY

I finished the 2014 NYC Marathon at an all-time low. I was injured and dejected after failing to meet my marathon goals on three attempts in three years. After battling back from injury I knew I needed help if I wanted to qualify for Boston (knocking at least 10 minutes off my best attempt).

I began working with Gary at the outset of my marathon training cycle with my sights set on the 2015 Chicago Marathon. His positivity, understanding of the science, and ability to adapt and customize my training to meet my specific needs were instrumental in my progress. With his guidance, I quickly PR’d at 5k, 10k, Half-Marathon and then in October I ran the marathon of my life, knocking more than 15 minutes off my PR and coming in nearly 6 minutes under Boston Qualifying time. And the crazy part? It was the easiest marathon I’ve ever run. No wall, no bonk, I trusted my training, I trusted my coaching, I trusted my race plan and I trusted my coach.

Thanks to Gary I was better prepared physically and mentally than I’d ever been. If you know what your realistic goals are, and you are 100% willing to do the work, Gary will get you there. I am unbelievably grateful for his coaching, and I firmly believe that I would not have been able to cross this huge goal off my bucket list without him.
