12+ years coaching Athletic & combat performance Hybrid training

Aaron Smith has been coaching strength and athletic performance for 12 years, working with everyone from weekend warriors to D1 collegiate athletes and pro fighters. His specialty is hybrid training — fusing maximal strength, explosive power, and aerobic capacity in programs that don't compromise one for the other.

His writing for FitNotes X focuses on the parts of programming that matter for people who want to be strong AND able to run, jump, fight, or play — not just bench more in a vacuum. Mobility, conditioning periodization, Olympic lifting, and the unglamorous fundamentals of recovery.

Aaron has a background in track athletics and Brazilian jiu-jitsu, and still trains both alongside lifting.
