Sound familiar?
From a 10-year-old who can't keep up to a pro who needs one more gear. If you read one and think "that's us" — you're in the right place.
Speed is a skill. We teach acceleration, sprint mechanics and first-step quickness — then build the strength behind it, and time it.
Playing isn't training. Structured, age-appropriate strength work builds the athletic base that games alone never will.
Movement quality comes first, loads progress only when technique is earned, and with 6–8 athletes per session every rep is coached.
Confidence follows proof. Monthly progress tracking shows her — in real numbers — that she's getting faster and stronger.
An ISSA-certified coach who has prepared MLB All-Stars, a plan for your child, and a free first class so you can see it yourself.
Mobility, landing and movement mechanics, and balanced strength — so a growing body can handle the demands of a full season.
We test what matters — speed, power, jumps and strength — log it, and train to move it. Numbers you can show and improve.
Bat speed is built in the legs, hips and core. Rotational power and lower-body strength train the engine behind the swing.
Velocity starts with force from the ground up. We build strength, power and mobility through the whole chain — not just the arm.
Conditioning built for baseball and softball: repeat explosive efforts and recovery between them — not long, slow miles.
Programs built around your sport, position and season, so strength in the gym turns into speed and power in games.
Strength and power training that builds force you can actually use — plus speed, so you play bigger than you are.
Sessions from 6:45 AM to 8:20 PM plus Saturdays, with a plan that bends around class, practice and travel.
8 and 12-week transformation blocks with start, midpoint and end testing. A target, a plan and proof you moved.
Durability is trained: mobility, movement quality and smart in-season loading so you can stay on the field and finish strong.
Separate yourself with numbers coaches respect — faster times, more power, more strength — tested at the start, midpoint and end.
Once your medical team clears you, we rebuild strength, speed and confidence step by step — and test it, so you know you're ready.
Train with us during summer and winter break: a structured block that keeps you progressing instead of starting over.
Coach Gianmarco has prepared MLB All-Stars and pro prospects. Elite players get their own rates, schedule and a plan built around their preparation.
Every block is planned around your schedule, your load and your recovery — precise training that keeps performance high all season.
Off-season blocks built backward from spring training: strength first, then power and speed, peaking right on time.
In-season maintenance that holds strength and power without leaving you flat on game day.
Training load matched to how you recover, so every session moves you forward instead of digging a hole.
We test strength, power and mobility through the whole chain to find the gap — then train it until the power comes back.

What we train
Our expertise is strength and conditioning for baseball and softball players, and for every high-performance athlete who wants to be faster, more explosive and stronger. No circuits for the sake of sweat. Every block has a target and a test.
01Acceleration, top-end speed and change of direction. First-step quickness on the bases and in the field.
02Jumps, throws and rotational power that turn strength into bat speed and throwing velocity.
03Progressive, coached lifting built around the athlete's sport, age and level. Strong first, then fast.
04Mobility and movement quality so athletes stay on the field all season, not just in the weight room.
Transformation programs
A fixed-length block with a plan for training, food and supplements, an evaluation at the start, the midpoint and the end, and metrics logged so the results speak for themselves.

Inside the work
Booking & cancellations
All training requires a reservation. Monthly members get priority for their regular slots; remaining spots open to weekly packs, single sessions and trial classes.
If you can't complete next week's sessions, let us know the Sunday before so we can try to reschedule. Changes depend on availability and must fall within your plan period.
Every cancellation or change needs at least 48 hours' notice.
Cancelling with less than 48 hours, the day before, the same day, or not showing up counts as a used session — not replaced or refunded. Advance notice lets us try to move you, but doesn't guarantee a new slot or extend your plan.
