Which gym training makes your tennis serve faster
Lift for the stroke. Turn strength into racquet speed.
Key facts
- 1
Strength and conditioning raised serve speed with an effect size of 0.79 for multimodal programmes and 0.53 for resistance training, while core-only work, at 0.32, was not significant.
Frontiers in Physiology, 2024 meta-analysis of 16 studies
- 2
A serve's acceleration phase lasts under a quarter of a second, far less than a muscle needs to reach maximal force.
- 3
Below a strength threshold of about 1.35 times bodyweight on the bench, heavy plyometrics pay less.

Hill's force–velocity curve shows a muscle trading force for speed, with power peaking in the middle.

Typical gym sessions by phase are 3–4 a week off-season, 2–3 pre-competition and 1–2 short ones in season to maintain.
Why it works
A muscle can be strong or fast, but not both in the same contraction. Tennis strokes are brief, so the quality that matters is rate of force development: how quickly you reach force, because the stroke ends before maximal force arrives. A big lift you can't express fast never reaches the strings.
Maximal strength still matters. A higher ceiling lifts the whole force–velocity curve. Rotational throws and the stretch-shortening cycle then convert that base into racquet-head speed in the stroke's own pattern: legs, hips, trunk, arms.
Order the week and the season to match. Within a session, do explosive work first, heavy work second and prehab last. Build in the off-season and maintain in season. A bodybuilding split adds mass the chain has to carry, and long slow running trains the wrong system and can blunt power.
The line to say on court“Strength is the tank. Rate is the tap.”
Drill: The rotational throw ladder
15 min · alone or with a partner- Throw a medicine ball side-on into a wall or to a partner, hips first, on both sides. Feel the order: legs, hips, trunk, arms.
- Do shotput throws, then overhead throws, in the same order, with full intent and full rest between.
- Finish with ten first serves measured on a radar or ball tracker. Log the median speed.
- Repeat the serve test on the same device six weeks later.

Faults and fixes
Questions players ask
Does core training make your serve faster?
Not on its own. In a 2024 meta-analysis, core-only programmes had an effect size of 0.32 and weren't significant, while multimodal programmes reached 0.79.
What should tennis players do in the gym during the season?
Maintain, don't build. One or two short sessions a week, such as one heavy lower-body lift, rotational medicine-ball throws and an anti-rotation core hold.
Do medicine ball throws help tennis?
Rotational throws follow the same hip, trunk and arm order as the serve, which is the case for them. Transfer from gym power to stroke speed is positive but variable.
Is running good for tennis power?
Long slow running trains the wrong system and can blunt power. Use intervals instead.
What this doesn't cover
Transfer from gym power to stroke speed is positive but variable, and the best load for power depends on the athlete. Sets, reps, loads and ball weight are for a strength and conditioning coach to set. This guide names qualities, not prescriptions.
