Why doesn't jogging cut it for a third set? Tennis needs HIIT, adductor strength, and core stability instead of endurance runs — the intermediate fitness plan.
Why doesn't pure endurance running keep you fresh in a third set? The honest answer: because tennis isn't an endurance sport — it's a sport of short explosions with lightning-fast recovery in between, and jogging trains exactly the wrong thing for that.
For advanced players, refining stroke technique alone isn't enough anymore. If you want to take your game to the next level and dominate matches into the third set, you need a physical foundation built for the massive demands of modern tennis.
Scientific research shows: tennis is a high-intensity, intermittent sport — it hammers both your anaerobic system (explosive rallies) and your aerobic system (fast recovery in the short breaks).
On top of that: muscular fatigue measurably degrades proprioception (your joint-position sense) — especially in the shoulder — which costs you precision and significantly raises your error rate. Pure endurance training through slow jogging is inefficient at this level. DOMISPORTS Academy instead builds a plan around HIIT for endurance, targeted adductor training for lateral speed, and intense core and transfer training for stable, explosive stroke power.
To run this plan efficiently off the tennis court: A gym mat: for essential core training. Compact dumbbells or kettlebells: to build strength in your legs and upper body. An agility ladder and jump rope: for reactive footwork and speed. A medicine ball (about 3 kg) and resistance bands: for rotational power and transferring strength into tennis-specific movement.
Tennis is constant switching between full sprints and short breaks — that's exactly what your cardiovascular system needs to be trained for. HIIT is the tool for the job.
How it works: run one to two sprint-interval sessions per week. Sprint 15 to 20 seconds at maximum intensity (anaerobic), then switch to 40 seconds of easy jogging (aerobic recovery). Repeat this cycle for 15 to 20 minutes. This trains your body to clear lactate faster and to bring your heart rate down effectively in the 20 to 25 seconds you actually get between rallies.
Explosive leg power is the foundation for a hard serve and a fast first step to the ball. Because tennis demands mostly lateral movement, your inner thigh muscles (adductors) especially need strengthening — they stabilize your joints during abrupt direction changes.
How it works: work in heavy lateral lunges with compact dumbbells, deep squats, and skater jumps. Do 3 to 4 sets of 8 to 12 reps. This strength gives you an extremely stable base even when you're pushed wide off the court.
An advanced player doesn't hit the ball with the arm — they generate power from the ground and transfer it through the hips and core into the racket. Without strong core stability, that power leaks away and your precision suffers massively.
How it works: skip basic crunches and focus on functional, stabilizing exercises instead. Planks with weight shifts, Pallof presses (anti-rotation with a resistance band), and dynamic trunk rotations strengthen your midsection — the bridge in your kinetic chain.
The most important piece for advanced players: actually transferring the strength you've built into the real tennis stroke. Speed training with agility ladders and plyometrics also trains the neuromuscular reactivity behind a sharp split step.
How it works: use a 3 kg medicine ball for rotational throws against a wall. Focus on timing and hip-rotation coordination — exactly like a forehand. Simulate the tennis-specific push-off from your back leg while you do it.
Advanced strength and plyometric sessions need well-prepared tissue. Start every workout — like every match — with thorough "muscle prep," like foam rolling and targeted mobility work for shoulders and hips.
Watch out: under fatigue, your joint proprioception drops — you execute movements less cleanly and overload ligaments. Pause high-intensity training if something hurts, and deliberately schedule recovery phases.
Look at how ATP/WTA tour pros actually train: elite coaches loop resistance bands around a player's hips while they perform shadow forehands or medicine ball throws.
The backward pull forces the player to drive hip extension forward and upward with real force to channel power into the shot. This combination of resistance and a 3 kg medicine ball integrates strength, coordination, and timing directly into your actual stroke mechanics.
Because tennis is almost entirely short, explosive sprints with immediate recovery — not steady-state pace. Long, slow jogging trains the wrong muscle fibers and tends to make you more sluggish on court, not faster. HIIT with 15-to-20-second sprints matches tennis-specific demands far more closely.
Because tennis demands mostly lateral movement — abrupt direction changes, deep lunges, sudden stops. Your adductors (inner thigh muscles) stabilize exactly those movements. If they're weak, your stance wobbles on contact, and your injury risk climbs. Targeted adductor training isn't optional extra work — it's core programming for any serious player.
Your power doesn't come from your arm — it comes from the ground, through your legs, hips, and core, into the racket. If your core isn't stable enough, that power leaks away along the chain, and you hit the ball noticeably weaker and less accurately, no matter how good your arm technique is.
One to two HIIT sessions a week cover the endurance side, plus two strength-and-core sessions. Always build in at least one full rest day — proprioception drops under fatigue, and that's exactly when most overuse injuries happen. Listen to your body, and shift the rest day earlier rather than later if needed.
Stop the high-intensity work immediately instead of pushing through. Pain under fatigue is a warning sign of declining joint stability, not something to train through. Focus on mobility work instead, and get persistent symptoms checked by a doctor. A few days off cost you far less than an injury you pushed through.
