Your Strength Training Feels Random and It Shows
You Never Know What To Do Or When To Do It.
You bounce between programs, YouTube workouts, and coach advice and still are not sure how lifting should fit around BJJ, MMA, or striking.
You Are Always Sore, Tight, Or Worried About Getting Hurt.
Hard lifting stacked on hard rounds leaves you beat up, makes you second guess takedowns, and leaves you feeling one bad rep away from a pull or tweak.
You Do Not Have The Time Or Energy For Long Gym Workouts
Hard lifting stacked on hard rounds leaves you beat up, makes you second guess takedowns, and leaves you feeling one bad rep away from a pull or tweak.
A Strength System That Finally Works With Your Fight Training
You Know Exactly What To Do Each Week.
Clear strength and conditioning sessions plug into your BJJ, MMA, or striking schedule so nothing fights for the same energy.
You Show Up To Training Feeling Strong, Not Wrecked.
Smart progressions build power and resilience while reducing the nagging aches and injury risk that used to hold you back.
You Can Finally Stick To A System.
Short, focused sessions fit a busy schedule, so strength work becomes a repeatable part of your routine instead of the first thing you cut when life gets busy.
About Zack
A Coach Who Lives in Combat Sports
I grew up wrestling and boxing before diving into Brazilian Jiu-Jitsu and Muay Thai. Across 17 years in martial arts, I have learned what fighters actually need from their strength and conditioning. For a long time I struggled to find training that fit combat sports, so I spent years coaching and studying exercise science to build a system that connects the work you do in the gym with how you feel and perform on the mats.
I have coached grapplers to tournament wins, supported fighters through MMA and Muay Thai camps, and helped hobbyists who train around busy lives build strength and confidence they never thought possible. I work with combat athletes at every level, from the first day on the mats to serious competition.

“Working with Zack has significantly boosted my explosive power, strength, and cardio. My in-ring recovery is faster than ever, giving me a second wind that made a huge difference in my last Muay Thai fight—I felt fresh while my opponent was exhausted.
