"Through Coach Samuels plyometric program my agility and hand speed increased tremendously.  The force behind each punch has drastically increased as well during the time spent with Samuels.  I would recommend Coach Samuels to anyone (except my opponents)."

Corey Johnson, 3-time Virginia Golden Glove Boxing Champion


"All my times and distances improved and I had fun working towards my goals.  Lu would tell me how a drill relates to my sport and it made me work harder.  I would want Lu as a coach for all of my sports."

David Shepard, former varsity football player, Rosemount HS


"Lu - you have made a very significant impact on Courtney's athletic performance.  Many individuals have commented on her improvements on speed, strength, agility and confidence.  How did she get there? You and your program at AthEnS have made the difference in making her into a better athlete.  We will definitely see you soon."

Deb Hopps, Soccer parent


"AthEnS is a confidence boosting, muscle building, endurance challenge that strikes a perfect balance between the mental & physical aspects of all sports.  The emphasis Lu puts on continual improvement within the bounds of safety was exactly what we, as parents, were looking for.  We will recommend Lu to all our friends with children in athletics.  We love it!"
