You hike South Mountain. You play 18 holes at Foothills Golf Club. You want to keep up with your grandkids. But lately your knee aches after the back nine, your back tightens on the downhill, and the energy is not what it used to be. You do not need a gym membership — you need a coach who understands your body and keeps you showing up.
Justin Sims is that coach. NASM-certified, kinesiology degree, 15+ years of experience. He has helped Foothills residents add 15 yards to their drive, get back to hiking South Mountain after knee surgery, and lose 47 lbs without crash diets. He only takes 5 new clients per month. Anytime Fitness Ahwatukee is a short drive north on 48th Street to Warner Road.
Justin Sims — The Coach Who Keeps Foothills Residents Showing Up
A college football injury ended Justin's playing career and started his obsession with how the human body moves, recovers, and adapts. That kinesiology and biomechanics foundation is why his coaching works — especially for the 55+ population that makes up a significant part of the Foothills community. He does not count reps from a clipboard. He watches every movement, corrects in real time, and holds you accountable week after week.

Training Programs for Ahwatukee Foothills Lifestyles
Golf Performance Training
The 85048 zip code is home to serious golfers — Foothills Golf Club, Ahwatukee Country Club, and Club West are all within minutes. Justin builds golf-specific programs targeting rotational power, hip mobility, core stability, and shoulder health. The result: more distance off the tee, more consistent ball striking, fewer rounds cut short by back pain, and the endurance to play 18 holes in Arizona heat without fading on the back nine.
Senior Fitness & Active Aging
The Foothills has a large population of active adults who hike, golf, travel, and want to maintain their independence. Justin's Functional Aging certification means he knows how to train older adults safely — improving balance to prevent falls, building bone density through progressive resistance, increasing joint mobility, and developing the functional strength needed for everyday life. Many of his 85048 clients are in their 60s, 70s, and beyond.
Trail & Hiking Conditioning
South Mountain's trails are minutes from the Foothills. Justin programs leg strength, cardio endurance, and ankle stability for hikers — whether you are tackling National Trail or just want to enjoy the Desert Classic without your knees protesting the next day. He also addresses the hip and quad strength needed for downhill sections, which is where most hiking injuries happen.
Weight Loss & Metabolic Health
Sustainable weight loss requires the right combination of resistance training, nutrition, and consistency. Justin does not prescribe crash diets or extreme programs. He builds progressive plans that work with your schedule and produce lasting results — clients regularly see improvements in bloodwork, energy, sleep quality, and body composition within the first 8-12 weeks.
Injury Recovery
Joint replacements, rotator cuff repairs, spinal fusions — these surgeries are common in the Foothills community. Justin works closely with your post-surgical timeline to rebuild strength and range of motion safely. His kinesiology background means he understands the biomechanics of recovery, not just generic exercise prescriptions.
What to Expect in Your First Session
- Goals & History Discussion — Justin sits down with you to understand your goals, injury history, daily activity level, and any medical considerations. No clipboard script — a real conversation.
- Movement Assessment — A series of functional movements that reveal mobility limitations, muscle imbalances, and areas of concern. This is where Justin's kinesiology background shines.
- Introductory Training — A modified workout that lets Justin see how you move under load, gauge your current fitness level, and start teaching proper form on foundational exercises.
- Custom Program Design — Based on the assessment, Justin builds your personalized training program — including what to do on your own between sessions.
