He grew up playing soccer into high school, when he added tae kwon do, ultimately earning a black belt, and teaching classes at the age of 17. Jon started running competitively on his high school track and cross country teams, which was when he was first introduced to weightlifting. Like many other young lifters, he was focused on looks over performance, and regularly skipped lower body days. Jon picked up softball, volleyball, and mountain biking in college, but still was drawn to the free weights. After a lengthy break from exercise that saw him gaining 25 lbs, Jon sharpened his diet, and re-entered the weight room, this time working on functional movements. In 2008 he discovered CrossFit, and did a few workouts on his own, but wasn’t ready to drink the kool-aid. After a knee surgery in 2009 he jumped into the CrossFit world with both feet.

She found CrossFit to be varied, challenging and fun and not time consuming. As a busy litigation attorney with her own practice, the time-saving element was very appealing. As a coach, Cindy loves watching a new CrossFitter gain confidence and skill over time and become an integral part of the Hammer Down community. CrossFit helped Cindy achieved her first sub 2:00 half marathon, without her having to run an excessive amount of miles each week. Always active as a swimmer, tennis and softball player in high school, in the last 25 years Cindy has run hundreds of races, triathlons and biathlons and takes yoga classes in addition to CrossFit.
