■ Action Checklist — Practice Steps from This Video:
1. Do a shadow swing and freeze your arm at the ideal contact point — about 45° out in front of your body — so you memorize the comfortable gap between your elbow and your ribs. 2. Place a ball between the baseline and service line as a bounce marker, then move from your ready position and plant your anchor foot (the foot on your dominant hand side) about two-thirds of a racket length to the side of the marker — 20 reps, then add a forward step and shadow swing for 20 more reps. 3. Plant your anchor foot on the court's center mark and keep it pinned until after contact, then step with your other foot to random points along an imaginary semicircle around that anchor foot, taking a shadow swing on each of 20 reps. 4. Play a live baseline rally while keeping your arm swing shape completely stable — no poking, reaching, or pulling with the elbow or wrist — so your legs and core handle 100% of the distance adjustment.
■ Video Summary
Most weekend players lose control on the forehand because their arm quietly compensates for spacing errors that the legs should be handling. This video breaks down why that happens and gives you four progressive drills to lock your arm structure in place and let your footwork manage the distance to the ball.
■ Why Save This Video?
Save this so you can retrain your legs to do the spacing work — it takes the strain off your arm and shoulder, which means less soreness and fatigue carrying into your work week.

Hi everyone, and welcome to Ru's Tennis Lab.
My name is Ru, and I'm a Japanese tennis coach currently working in Brisbane, Australia. I studied sports science in Australia to understand the logic behind the movement. I believe that logical guidance based on physics is the fastest way for adult players to improve without relying on pure athleticism.

What we are going to achieve is the exact physical sensation of consistent forehand rally
with accurate spacing done with your legs and nothing with your shoulder during the forward
swing. But let's talk about what's actually happening on court. You either find yourself
reaching your arm out widely for a short ball or your contact point gets pushed back because you
blindly step forward into a heavy ball. We're going to train you to hit with your legs, not
your arms. Let's get started. To fix the forehand, what I've noticed is that we must adjust our
distance to the incoming ball explicitly using our feet. The secret is keeping your hitting
arm structure completely locked in its optimal shape, letting your legs manage the space.
Now here's the first instinct for most weakened players. They try to adjust the correct distance
using the hitting arm. In my experience watching this movement, that's a trap. What we want is the
appropriate space between yourself and the incoming ball during the contact. By reaching out or tucking
your hitting arm in right before the contact, you're losing the balance and ruining both the power
and control of your forehands. To build this interior muscle memory, let's break it down into
four concrete practice steps you can do on court. Step one is the contact freeze. You're going to do
a shadow swing and pause your arm completely at the ideal contact point, committing to memory exactly
what that 45 degree out in front extension point looks like and feels like. When you do this
correctly, you will feel a clear comfortable pocket of space between your elbow and your ribs.
Your arm should feel stable and supported, not overextended and not cramped against your shirt.
Step two, the anchor foot. The split second you recognize the ball's trajectory, you must find the
correct position for your anchor foot, the foot on your dominant hand side. This foot acts as your
body's anchor. You want to place it about two-third length of the racket to the side of the ball's
expected bounce point. To the left for right handers, to the right for the left handers.
Place a tennis ball anywhere between the baseline and the service line to mark the simulated bounce
point. Start in your ready position about three steps away from that marker. Move and place your
anchor foot about two-third length of the racket to the side of the marker. Repeat this 20 times to
lock in the visual distance. Next, add a forward step with your other foot and complete a shadow swing.
Repeat this full sequence another 20 times. This drill is specifically designed to help you train
and judge the correct sideways distance between your anchor foot and the bounce point. If this
initial step is lazy or inaccurate, your spacing is ruined before the swing even begins. Avoid
stepping directly next to or past the bounce point which will leave you jammed. Step three, the
semi-circle drill. Once your anchor foot is set, your non-dominant foot takes the stance step
to finalize your spacing. If the ball is short and low, you'll step forward and into the court.
If the ball is deep or fast, your stance will be more open. No matter where the ball lands, the
stance step ensures you always strike the ball at that perfect 45 degree angle in front of your body.
Place your anchor foot directly on the court's center mark. This foot stays pinned and cannot
move until after contact. Imagine the semi-circle drawn on the court around your anchor foot.
Practice taking your stance step with your other foot to various random points
along this semi-circle, executing a shadow swing each time. Repeat this 20 times.
This brings us to step four, the stable arm long rally. Enter a live baseline rally
where your arm swing shape must remain completely stable and unchanging, with absolutely no poking,
reaching, or pulling with the elbow or wrist. You're forcing your legs to do 100% of the movement
and distance adjustment. As you strike the ball, you'll feel your core and legs working twice as
hard to track the ball's bounce, while your hitting shoulder feels completely relaxed,
almost like a passive passenger enjoying the ride driven by your lower body. Now you might
be thinking, Bru, if a ball is blasted deep into a corner at 80 miles an hour, I don't have time to
step around and dance with my foot. In an emergency situation like a defensive dead sprint out wide,
you would be right. You do what you have to do to survive. But here's what I've noticed for
players focused on consistent, efficient performance during normal baseline rallies.
When you rely on the arm out of pure habit rather than emergency, you give away all control. Watch
out for that unconscious urge to revert arm poking or lunging the moment a deep ball catches you by
surprise. Be highly aware of lazy feet syndrome during fast transitions. If your feet stop
adjusting, your arm will automatically try to save that shot. And that's the secret to keeping your
foundation rock solid under pressure. If this kind of clear, step-by-step breakdown you can use
right away is useful to you, hitting that subscribe means you won't miss similar videos. To truly break
this habit, we have to look at why it happens. What I've noticed is a core misconception that
tennis power comes from primarily from shoulder. Because of this, your brain defaults to making the
final micro-adjustments with your arm. Additionally, let's be honest, it is mentally and physically easier to
manipulate the lightweight arm than it is to move the heavy legs. Here's what tends to happen.
Because your brain thinks the arm generates the power, your feet freeze. When the feet freeze,
you're forced to flail your arm to reach wide or deep balls, or you get completely jammed up when
the ball bounces deeper than expected. The erratic arm movement isn't a real problem, it's just a symptom
of your legs refusing to hunt for the optimal space. Look at the difference side by side. On the left,
the classic struggle. Static feet, a frantic arm, completely at the mercy of the ball's depth.
On the right, look at how quiet the upper body is because the legs are doing the heavy lifting.
Mastering this precise spacing doesn't just fix your balance, it sets up a beautiful chain reaction.
Once your anchor and stand steps position you perfectly every time, this mechanical error is
often completely unconscious. Save this video to your phone right now so you can replay and review
