Off-Court Training for Junior Tennis Players ft. Dean Hollingworth

Summary

Dean Hollingworth — Montreal-based master tennis performance specialist (ITPA), certified strength and conditioning coach, PTR board of education member, and former travelling fitness coach to Eugenie Bouchard and Elena Vesnina — answers parent-submitted questions about off-court physical training for junior tennis players. The episode covers appropriate training volume and timing by age, the difference between a tennis-specific fitness coach and a generic speed/agility facility, the priority of body movement patterns (push, pull, squat, hinge, rotation, locomotion) over bodybuilding-style isolation work, the kinetic chain and why power starts from the ground up, injury prevention principles (particularly ankle rehabilitation), and the specific content that belongs in a junior player’s tennis bag for daily preparation. This is the most practically detailed ParentingAces episode on physical training for juniors.

Guest Background

Dean Hollingworth has been involved in the tennis world for approximately 15 years as a tennis fitness specialist, with a broader strength and conditioning career spanning approximately 25 years. He holds master tennis performance specialist certification from the ITPA (founded by Mark Kovacs), PTR board of education membership, RACAFIT certification, and a certified strength and conditioning coach credential. He has worked with players ranging from age 8 through the WTA level, including travelling with Eugenie Bouchard during her competitive peak and with Elena Vesnina (world number one in doubles). He is based in Montreal, Canada and runs his physical training and video content platform under the Baseline Power brand (@baselinepower on Instagram; baselinepower.com for video training series).

Key Findings

1. Training Volume and Format Changes Completely by Developmental Stage

At 8-12: 10-15 minutes of movement work per session, playful and unstructured, focused on learning through experience. At 12-14: 30 minutes of movement training three to five times per week, performed BEFORE getting on court (when the athlete is fresh), focused on tennis-specific movement patterns. As the athlete gets older: two to three sessions per week in the gym, 40-45 minutes maximum per session, emphasizing functional movements before isolated exercises. The critical rule: off-court training should be done before on-court training, not after. You cannot develop motor patterns, acceleration, and explosiveness in an already fatigued body.

2. Generic Speed/Agility Facilities Are a Mixed Bet — Tennis-Specific Background Is Non-Negotiable

Many speed/agility facilities advertise athletic development but lack understanding of tennis-specific movement: the split step, the lateral shuffle, the recovery base, the crossover step. Hollingworth will not tell a parent to never use these facilities — some do excellent work — but his criteria are clear: the trainer must have tennis background (certified tennis professional or equivalent), a genuine strength and conditioning credential (CSCS, ITPA), and must run sessions with appropriate supervision ratios. The statistic: 70% of gym injuries are caused by lack of supervision. A football assistant strength coach running a women’s college tennis team’s S&C program — which Hollingworth has witnessed at high-level D1 programs — is a failure of institutional process, not individual coach quality.

3. Train the Movement Patterns the Body Actually Performs — Not Isolated Muscles

The human body performs six fundamental movement patterns: push, pull, squat, hinge, rotation, and locomotion. A junior player’s off-court training should be organized around these patterns, not around bodybuilding muscle groups (chest and back day, biceps and triceps day). Squats, split squats, lateral lunges, and rotational exercises are foundational before anything is loaded. Hollingworth’s sequence: body weight mastery first, resistance bands and light loads second, progressive loading third. A 12-year-old who has never trained should not be doing the same program as a high-level 12-year-old who has been training for two years — fitness age, not chronological age, determines the appropriate starting point.

4. The Athletic Ready Position Is the Foundation of All Movement

Hollingworth’s definition of the “athletic base”: feet slightly wider than shoulder width, quarter squat depth, hips pushed back (not knees forward), heels slightly off the ground, active and ready to push. Research shows that 70% of balls a player will receive are within a 2.5-meter radius of their current position. Mastering explosive movement within that three-meter bubble — getting there on time, in balance, with the racket in attack position — wins more points than any other skill at the developmental level. Most junior players stand passively with flat feet and locked knees between points; getting into and maintaining the athletic base is a correctable technical error.

5. The Number-One Predictor of Injury Is Past Injury

This is stated as a clinical principle: past injury is the strongest predictor of future injury. An ankle sprain that is allowed to recover without specific ankle strengthening work leaves a weakness that will repeat. Hollingworth’s ankle rehabilitation sequence: single-leg standing barefoot with eyes closed, progression to proprioceptive surfaces (bosu ball), calf raises, and specific band work. The same principle applies to shoulder and hip injuries — the site of past injury must be actively strengthened and stabilized, not just rested until pain resolves.

6. Power Starts from the Ground Up — Not from the Shoulder

The single most common misconception parents bring to Hollingworth: that a stronger shoulder produces a stronger swing. This belief directly causes shoulder injuries, because players and coaches focus strengthening efforts on the wrong part of the kinetic chain. Power production runs: ground → legs → hips → core → shoulder (which decelerates and stabilizes the swing). A tight hip restricts hip rotation; the lower back (which is meant to be stable, not mobile) then attempts to compensate by rotating; injury follows. Tennis-specific shoulder exercises (external rotation at 90 degrees and zero degrees, band T’s and Y’s, X-patterns on a Swiss ball) maintain the shoulder’s deceleration function — but they are not the power source.

7. Warm-Up Should Mirror What the Body Will Do in Competition

Hollingworth’s ideal warm-up structure: foam rolling the body before getting on court, barefoot dynamic exercises (the world’s greatest stretch, lateral lunges, rotational movements), resistance band activation (glutes, hip flexors, ankle complex), then tennis-specific movement patterns (sprint, shuffle, backpedal, crossover) before a single ball is hit. The body’s first sprint of the day should not happen on a match point. He specifically emphasizes backpedaling as underemphasized in junior development — players are often awkward in backward movement and many injuries occur during backpedaling when balance and hip stability fail.

8. Standard Equipment for Every Junior’s Tennis Bag

Hollingworth provides a specific list: resistance band(s) at least one resistance level, resistance tubes, a short foam roller (available on Amazon, should travel to every practice and tournament), and a lacrosse ball or baseball for foot and soft tissue work. These items together cost less than a single private lesson and, used consistently before every practice and match, address the most preventable injury causes in junior tennis.

Actionable Advice for Families

• If your child’s warm-up before hitting consists of a few forehands and a quick stretch, replace it: 20-30 minutes of movement prep before any practice or match, starting with foam rolling and barefoot dynamic work, is the single highest-leverage change most junior families can make immediately
• Prioritize finding a fitness coach with dual credentials in tennis movement AND strength and conditioning, rather than a sports performance specialist without tennis experience — the split step and tennis movement patterns are not transferable from football or basketball training
• Do not delay ankle rehabilitation until the pain is completely gone; the moment a sprained ankle can bear weight, specific ankle strengthening work should begin to prevent the recurrence that statistics predict

INTENNSE Relevance

• Physical preparation as league standard: Hollingworth’s warm-up protocol (foam rolling, barefoot activation, band work, tennis-movement patterns) could be formalized as INTENNSE’s pre-match warm-up standard — a visible, broadcast-worthy ritual that differentiates the league’s professionalism and signals to players and fans that physical preparation is taken seriously
• Strength and conditioning partnerships: A league-wide partnership with a certified ITPA or CSCS trainer for team S&C coordination would provide the kind of dual-credential expertise Hollingworth describes as non-negotiable, while creating a shared development philosophy across all 10 INTENNSE team staffs
• Kinetic chain and coaching language: The kinetic chain framework (power from the ground up, not from the shoulder) is a coaching language that INTENNSE mic’d coaches can use in-match to explain shot selection and player performance — technically accurate, immediately understandable to broadcast audiences, and demonstrating the coaching intelligence that distinguishes the product
• Injury prevention and unlimited substitutions: Hollingworth’s injury prediction principle (past injury is the strongest predictor of future injury) directly intersects with INTENNSE’s unlimited substitution structure; coaches who know a player’s injury history can substitute proactively, managing load without sacrificing competitive contribution
• Athlete longevity culture: Hollingworth’s “less is more” philosophy — quality over volume, proper preparation over raw volume — is the athletic culture INTENNSE should build into its player development model from the first year of the league

Notable Quotes

“I will help them become a better athlete. Because the better athlete you have, the better tennis player you’re going to see.”

“The number one predictor of injury is past injury.”

“If you really think the shoulder is producing the power for your forehand, you are going to have shoulder problems.”

“70% of the balls a player will receive are within a 2.5-meter radius of their current position. If you can get really good at that three-meter bubble, that’s 75% of the shots.”

“I’d rather see an athlete on the court for an hour and a half working hard than three hours of work that isn’t truly up to par.”
