Tyler Schaeffer CSCS, SFG II, Personal Trainer , Head Strength & Conditioning Coach

Tyler Schaeffer is a Certified Strength and Conditioning Specialist (CSCS) by The NSCA, a USA Weightlifting (USAW) Level I coach and an SFG Level II Certified Kettlebell nstructor. Growing up in Las Vegas, NV, Tyler played football and baseball at the varsity level while working with several strength coaches and personal trainers in order to maximize his potential on the field. The work in the gym paid off with the opportunity to play football at the college level for Grinnell College in Iowa.
After college Tyler decided to pursue his passion of fitness and athletics by helping others achieve their physical goals, whether that play sports at a competitive level or simply live a healthy and fit lifestyle.

Tyler's philosophy is the same as F5 Fitness: If you train like an athlete, you will function, look, and feel like an athlete. To excel on the field, athletes must be in phenomenal shape, and it is no secret as to how they achieve this level of fitness. The same compound lifts, plyometric movements, and conditioning programs that reward athletes will also reward the general public. We all do not have the genetics to become professional athletes, but we can train ourselves to our genetic potential.
