How to Throw Harder — Safely
Adding velocity is not about throwing more. It is about throwing better, getting stronger, and recovering fully. Done right, most high school pitchers add 3–6 mph in an offseason. Done wrong, they end up in the training room.
The three drivers of velocity
1. Long toss
Extend your throws to comfortable max distance 2–3x per week. Long toss builds arm strength and integrates lower body drive.
2. Lower-body strength
Velocity is 60% legs. Trap-bar deadlifts, split squats, and hip-hinge power transfer directly to mound force.
3. Mechanics and mobility
A stiff hip or slow front side caps velocity. Daily hip and thoracic mobility plus qualified mechanical coaching are worth more than any weighted-ball program.
A sample week
Do this in the offseason. Cut volume by 40% in-season.
Monday
Long toss + lower-body strength.
Tuesday
Bullpen (light) + arm care + upper-body pull.
Wednesday
Recovery: mobility, easy catch, sleep.
Thursday
Long toss + lower-body power (med ball, box jumps).
Friday
Command bullpen + arm care.
Weekend
One full rest day; one light throwing + mobility day.
What to avoid
No weighted balls under age 14. No max-effort bullpens without a proper warm-up. No ignoring pain — arm pain that persists more than 48 hours needs a doctor, not more throwing.
Frequently asked questions
Do weighted balls work?+
Yes, when programmed by a qualified coach for pitchers 14+ with sound mechanics. On their own, unsupervised, they cause injuries.
How many bullpens per week?+
Two in the offseason (one light, one command). One in-season on your throw day between starts.
How much can I add in a year?+
Most 15–18 year olds add 4–8 mph in a full offseason with structured training. Late bloomers can add more.
