Breakside Strength and Conditioning brings you the best in ultimate training methodology straight to your mobile device. Founders Charlie Eisenhood and Pat Kelsey are both NSCA Certified Strength and Conditioning Specialists and ultimate players with a combined 30 years of experience playing, coaching, analyzing, and programming workouts for ultimate athletes.



Program Philosophy

Our philosophy is driven by the unique movement, strength, and energy needs that ultimate demands. We seek to build fast, powerful athletes with a science-driven combination of resistance training, sound conditioning principles, and speed and agility development.

There is truly no other sport like ultimate, so our training must reflect that. Ultimate players do not yet have the guidance and coaching in strength and conditioning that other sports have in the youth and college setting, and injuries often befall athletes with that lack of education. We believe that everyone should have access to world class strength training and injury prevention.

Breakside Strength & Conditioning is committed to providing those resources to ultimate players at all levels, from beginners to the pros.
