Glenn Seth

Master Trainer

Glenn has been training with kettlebells for ten years after serving as a US Marine and has certifications from World Kettlebell Club (WKC), Russian Kettlebell Challenge (RKC) and ACE. He has trained with world class athletes Valery Fedorenko and Catherine Imes. Glenn's unique teaching approach to kettlebell training focuses on the flow which, along with fitness and function, give F3 its name (rated best Kettlebell workout by Washington post). At F3 Training and Bodywork, Glenn and his team offer a progression program for new clients to advance their kettlebell practice through four stages called Path of the Warrior. Glenn instructs master kettlebell sessions for his most advanced members. For advanced students and local trainers Glenn offers DC's only kettlebell certification program - The VonSeth Method.

Jenny Harlett

Head Trainer

Jenny came to F3 after finding herself bored and frustrated with lack of results at the gym. That was three years ago, and she has never looked back. A writer by trade, Jenny is a huge believer in the importance of women building muscle strength, especially as we get older. After working with master trainer Glenn Seth for 2.5 years, she jumped at the chance to become a certified F3 coach in February of 2014. It is Jenny’s goal to help DC women (and men!) realize their strength potential for lifelong health.

 
 
 
 

Coach Danny Lamas

Danny is a Kettlebell Coach at F3 and has trained under Master Trainer Coach Glenn Seth since 2011. He has a B.A. from George Washington University in Political Science and has worked as a human rights activist and program officer in the Washington area for seven years. He was inspired to take up kettlebells as an enthusiast of author Tim Ferriss’ books on entrepreneurship, learning, and fitness. The efficiency of full-body kettlebell workouts in improving functional strength and producing rapid fat loss inspired him to become a regular at Studio F3’s master sessions for more than two years and become an instructor for beginners. Danny attributes Glenn’s sessions with always having a new and exciting challenge through consistently varied workouts.

 

 
 
 
 

Coach Katy Hospital

Katy came to F3 in July of 2013, with no weight lifting experience and arms that bore a striking similarity to those of a T-Rex. A year and a half later, Katy is now a firm believer in F3 and master trainer Glenn Seth’s approach to building strength and wellness safely in a supportive small group environment. Katy credits kettlebell training with her improved strength, flexibility, and cardio health and has been a certified F3 coach for over a year.
