Athlete Performance & Sports Performance Training in Fremont
Move better before asking your body to do more.
Core Performance Chiropractic & Sport offers sports performance training in Fremont for athletes and active people who want their bodies to hold up to more. Athletic performance isn’t only about getting stronger or faster. How well you move, how much training your body tolerates, and how you recover all decide how far you can push.
Dr. Alex Lee finds the physical qualities limiting your performance, like restricted mobility, poor control, or low capacity for your sport’s demands, and builds a plan to improve them.
Performance Starts With What Your Body Can Actually Do
Before your body can consistently produce more, it needs the movement, control, and capacity to handle what you’re asking of it.
One athlete is strong but stiff. Another is mobile but can’t control that range under speed. A third moves well but can’t hold up to a full season of training. We figure out which of these is holding you back, then work on it.
Who Athlete Performance Care Is For
Competitive Athletes
Athletes who train and compete often and want their bodies to hold up through practice, games, and recovery.
Recreational Athletes
Golf, running, pickleball, tennis, basketball, rec leagues, and cycling all put real demands on the body, whether or not you compete.
Strength & Fitness Athletes
Lifters who want to keep progressing while improving mobility, positions, and movement quality under load.
Youth Athletes
Young athletes benefit from building coordination, strength, balance, and body awareness as their sport gets more demanding. See our care for kids and teens.
Athletes Returning to Full Training
You might be past an injury but not ready to train at your old level yet. Performance work bridges that gap.
Active Adults
The same principles help anyone who wants to move well, stay strong, and keep doing what they enjoy.
Your Athlete Performance Assessment
Improving performance starts with knowing your starting point. Depending on your sport and goals, the assessment looks at:
Hover any point on the wheel to see what it means for your recovery.
Mobility
Whether you have the range of motion your sport requires.
Stability & Control
Whether you can control that range while producing force, landing, rotating, or changing direction.
Strength
Whether you can create and absorb force, hold positions, and tolerate training.
Movement Quality
Restrictions and compensations that quietly change how you run, jump, lift, or swing.
Balance & Coordination
How well different parts of the body work together as speed and complexity increase.
Capacity & Recovery
Whether your body can handle the volume and intensity you want, and how well it recovers between sessions.
How We Build Athletic Performance
Corrective Exercise
Chosen for the specific limitations your assessment turns up.
Mobility & Movement Training
Improving access to the positions your sport needs, with Functional Range Conditioning (FRC) principles.
Chiropractic Care
Adjustments when joint restrictions are limiting movement. One part of the plan. Learn about chiropractic care.
Strength & Stability Work
Targeted exercise to build force, control, and capacity.
Active Release Technique
Hands-on soft tissue treatment for tight or restricted muscles. Dr. Lee is a full body A.R.T. provider.
Recovery Technologies
Tools like NeuFit and red light therapy when they support your training. See recovery technologies.
From Sports Rehab to Performance
Rehab and performance aren't separate worlds. Rehab gets you back in the game. Performance work prepares you for what the game demands. See our sports rehabilitation.
Settle the Pain
An athlete coming back from injury starts by calming symptoms.
Restore Movement
Regain the range and control the injury took away.
Build Strength
Rebuild force and control in the areas your sport loads.
Load Tolerance
Gradually handle more volume and intensity without setbacks.
Athletic Movement
Reintroduce sprinting, jumping, cutting, and rotating.
Full Training
Return to full training and competition, prepared for what it demands.
Mobility Only Helps If You Can Control It
Athletes often hear they need to be more flexible. Sometimes that’s true, but extra range doesn’t improve performance unless you can control it at speed and under load. A golfer needs rotation and control through it. A runner needs hip and ankle movement plus the strength to repeat it thousands of times.
Our mobility training for athletes uses Functional Range Conditioning (FRC) principles to build usable, controlled range. Learn more about our mobility training.
Building an Athlete Who Holds Up
Strength That Supports How You Move
Athletic strength should carry over to the positions and movements of your sport, not just a bigger number on the bar. That may mean single-leg strength, hip strength, rotational strength, core control, shoulder stability, or the ability to absorb force when you land and cut.
Build the Capacity to Handle Your Sport
Doing a movement once is different from repeating it across a game, a tournament, a long run, or a full season. Capacity is your body's ability to handle that repeated demand. We find where you need more strength, endurance, or gradual exposure to higher training loads.
Injury Prevention for Athletes
No program can guarantee you won't get hurt. What you can do is get better prepared: improve strength, mobility, control, balance, and load tolerance so your body handles its demands with more margin. The goal is removing unnecessary weak points, not building a perfect athlete.
We Work Alongside Your Coach or Trainer
Sports Performance Training by Sport
Runners
Repeated impact, thousands of times per run. The focus is lower-body strength, mobility, control, and running tolerance.

Lateral movement, quick stops, rotation, and shoulder health, plus the endurance to keep playing.
Golfers
Rotation, hip and upper back mobility, balance, and the strength to repeat the swing for a full round. See golf performance.
Basketball Players
Jumping, landing, sprinting, and cutting, with the lower-body strength to absorb all of it.
Soccer & Football Players
Acceleration, deceleration, direction changes, single-leg control, and tolerance for contact and repeated sprints.
Strength Athletes
Mobility, stability, and positions that let you handle progressively heavier training.
When to Consider an Athlete Performance Assessment
- You feel physically limited in your sport or training.
- You're strong but restricted in certain positions.
- You're mobile but struggle to control movement under load or speed.
- The same areas keep getting tight or sore.
- You're returning to higher-level training after an injury.
- You're increasing your training volume or intensity.
Why Athletes Choose Core Performance
A Clinician Who Competed
Dr. Lee played college baseball on a scholarship at Simpson University. His own injuries as an athlete are what led him to chiropractic, and as a chiropractor for athletes, he knows the pressure to perform.
Extremity, Soft Tissue & Mobility Training
He’s a Certified Chiropractic Extremity Practitioner (CCEP), a full body A.R.T. provider, and uses Functional Range Conditioning, so shoulders, hips, knees, and ankles get as much attention as the spine.
Rehab and Performance in One Place
If an injury is still limiting you, rehab and performance work happen in the same plan.
Built Around Your Sport
A runner and a golfer need different things, and so do their plans.





Athlete Performance FAQs
What is sports performance training?
Sports performance training improves the physical qualities behind your sport: mobility, strength, stability, coordination, capacity, and recovery. At Core Performance it starts with an assessment of what your body does well and what’s limiting it.
Is this the same as working with a strength coach?
No. A strength coach handles your training program and conditioning. We focus on the clinical side: assessing movement, fixing restrictions and weaknesses, and treating anything that’s limiting you. The two work well together.
Do I need to be a competitive athlete?
No. We work with competitive athletes, weekend athletes, lifters, and active adults. If you care how your body moves and performs, the same principles apply.
How is athlete performance different from sports rehabilitation?
Sports rehab starts because an injury or pain is limiting you. Athlete performance focuses on improving the qualities that support higher-level training. Many athletes start with rehab and move into performance work as they recover.
Can athletic performance training prevent injuries?
No program can guarantee that. Improving strength, mobility, control, and capacity can help your body handle its demands better, so the focus is readiness, not a promise.
What happens during an athlete performance assessment?
Dr. Lee reviews your sport, training, goals, and injury history, then assesses mobility, strength, stability, balance, and movement quality. You leave with a clear picture of what to work on first.
Can I do this if I'm not injured?
Yes. Many athletes come in because they feel restricted or want to improve, not because something hurts.
How quickly will I improve?
It depends on your starting point and what needs to change. Some mobility changes show up quickly. Building real strength, capacity, and sport readiness takes longer, and that’s the kind of progress that lasts.
