Coach's verdict
You bring high energy and quick footwork to the court, but airborne contacts and unstable bases are bleeding away your control. When the ball gets up around shoulder height, you leave your feet and slap across the ball rather than driving up from a firm ground base. That leaves you vulnerable against deep incoming balls because you cannot control the depth or shape of your reply. Anchor your feet on high balls and let your hips lead the swing, and your power will translate directly into heavy, penetrating depth.
Fix this first
Jumping into high forehands robs you of control — Drill: 3 sets of 10 high-feed forehands where both shoes must stay pinned to the hard court through contact — Why: planting your feet forces your trunk rotation to do the work instead of letting your arms slap while airborne.

Technique
Your swing paths show good racket-head speed, especially when you commit to brushing up the back of the ball. The main mechanical issue is an overactive upper body that tries to muscle high balls instead of driving from the legs. You also chop down with an open face when rushed rather than keeping a steady unit turn. Cleaning up your spacing and maintaining a quiet head at contact will immediately steady your trajectory.
Movement & Footwork
You move fluidly across the baseline and react quickly off your toes. The breakdown happens on balls that push you back or float deep, where you tend to jump into the contact zone instead of setting your back foot and transferring weight forward. That floating base compromises your balance and delays your recovery. Work on planting the outside foot firmly to redirect your momentum back toward the center of the court.
Consistency
Your contact point wanders between waist and shoulder height, creating large swings in ball depth and shape. When you stay grounded and hit between waist and chest, you produce clean topspin with decent clearance. As soon as you jump or swipe at shoulder height, the ball flattens out and runs high risk of sailing long. Solidifying your spacing will keep your strike zone predictable.
- You strike the ball cleanly in the center of the strings at 0:01 when the contact zone sits right around waist level.
- At 0:04, the ball comes off the bottom of the string bed due to a hurried, descending angle of attack on the slice.
- Your contact point at 0:09 occurs slightly behind your lead hip, preventing full extension out toward your target.
- The flat drive at 0:12 travels on a direct, low-margin trajectory because of your level swing path at shoulder height.
- On the overhead at 0:14, you time the apex accurately and find the sweet spot with full upward extension.
- Racket-face stability is clean at 0:01, maintaining a neutral angle through impact without twisting in your hand.
- Variable contact heights across repetitions prevent you from establishing a repeatable, deep rally arc over the net.
Mental Game
You maintain continuous motion on your toes throughout the hitting sequence and keep your eyes tracking the ball. You also transition smoothly between different swing types without pausing your footwork.

Focus areas, in order
- Jumping into high forehands robs you of control — Drill: 3 sets of 10 high-feed forehands where both shoes must stay pinned to the hard court through contact — Why: planting your feet forces your trunk rotation to do the work instead of letting your arms slap while airborne.
- Chopping down too steeply on defensive forehands leaves balls short — Drill: 20 repetitions of knee-height feeds focusing on a level, carving follow-through out toward the net post — Why: leveling the swing path stabilizes the ball flight and keeps the slice skidding deep.
- Contact point gets pushed behind your body on deep balls — Drill: 15 shadow swings with an alignment stick placed one foot ahead of your lead toe — Why: visually training contact in front prevents you from getting jammed at your chest.
- Racket-head speed drops when reaching for wide balls — Drill: 3 sets of 8 medicine-ball lateral scoop throws from an open stance — Why: building core rotational strength ensures you can whip the racket head even when stretched out wide.
- Dropping your left tracking arm too soon on the overhead smash — Drill: 15 overhead shadow reps holding your non-dominant hand pointed toward the ceiling until the racket drop completes — Why: keeping the left arm raised preserves shoulder tilt and stops you from pulling down into the net.
- Delayed recovery steps after striking the ball — Drill: 10 forehand-to-recovery agility cone sprints with immediate crossover push-offs — Why: trains your outside leg to brake and fire back toward the center without crossing your feet awkwardly.
- Flat swiping through shoulder-height balls causes unforced errors — Drill: 20 feeds focused on a heavy upward low-to-high brush against high-bouncing balls — Why: adding shape and net clearance gives you safety margins when attacking floating balls.
