Here is what you've got in that notebook page — it's a coaching note comparing two backswing mechanics, probably for tennis/pickleball (you write "racket," "FH & BH stroke").
Back Swing ① number 8 figure style
② Straight Back Style
[boxed note on right]
Can be used for both FH & BH stroke
The racket top must be pointed toward the oncoming ball, so the racket is in front of the body & then the contact will also be well in front.
The middle doodle is the key. You've drawn a sideways figure-8 / infinity loop with arrows going around, and you've circled the "Right Hip" as the pivot. The arrows show the racket traveling down and around, then up, then back down again — not just straight back and straight forward.
It's messy on purpose — that's how coaches sketch a continuous motion path.
In short: you're teaching yourself to replace a linear, stop-start backswing with a continuous, hip-driven small loop. The loop gives you adjustable power and smoother timing, and it works for both sides because the prep (tip to ball, racket in front) is the same.
It reads like a personal reminder from a lesson — the kind of note you'd glance at before hitting to avoid pulling straight back when you're rushed.
Want me to turn this into a clean diagram of the figure-8 path around the right hip for FH and BH?
Why does the small loop give you "unlimited energy" while the straight back limits it?
How would this work for my backhand specifically — same loop or mirrored?

It's not literally unlimited, it's unlimitedly adjustable — and that's the whole point of your note.
The small loop wins because it never makes the racket stop. The straight back does.
With a straight back, you pull the racket back, it hits zero velocity, then you have to restart it forward from dead still. Physics hates that. You have to generate 100% of your swing speed in that tiny forward window, using mostly your arm and shoulder.
With the figure-8, the racket is always moving in a circle. You drop it down and around your right hip, then up and through. Because it's already in motion, you don't restart — you just redirect the momentum that's already there. That's why you wrote "force from the backswing could be regulated." You can bleed speed off by making the loop tighter, or add speed by letting the loop get a little wider, without ever pausing.
Think of pushing a kid on a swing versus lifting them from the ground each time. The loop is the swing.
When you trace that small infinity around the hip, your hitting arm externally rotates and your chest stretches across. That loads the big muscles — lats, pec, forearm — like a rubber band. It's called the stretch-shortening cycle.
In the straight back style ("no transition of racket"), there's no stretch. You just cock the arm back statically. No rubber band, no free energy, so you have to muscle it. If you try to muscle harder, you wrote the result yourself: "if too much, error occurs" — you tighten, the face wobbles, timing goes.
The magic of an infinity loop is you have two curves: down and up. If the ball is fast, you shorten the bottom of the loop and go. If it's slow or high, you let the racket ride the loop a fraction longer. The racket tip stays pointed at the oncoming ball the whole time, so you're never late, you're just adjusting the size of the circle.
A straight back gives you one decision: when to go forward. Miss that millisecond and you're either jammed or reaching. That's the "energy is limited" part — your power window is fixed by how far back you took it.
That's also why you circled "Right Hip." The loop isn't an arm trick. The hip turns back, the hand drops around it, then the hip fires forward and the arm gets slung through. The loop connects the lower body to the racket. Straight back disconnects them.
Your note to "make this small loop" is the coach's compromise. Big loops give more power but take too long. A compact figure-8 keeps the continuity, the stretch, and the adjustability, but stays in front of your body so contact stays "well in front" — exactly what you wrote at the bottom.
So: straight back = you create power from zero every time, limited and brittle. Small loop = you recycle momentum, load the body, and dial the power up or down inside the same motion.
Your note is right: it can be used for both FH & BH stroke. The principle is the same — a small continuous loop that lets the racket transition from front to back without stopping. The shape mirrors across your body, and how pronounced it is depends on whether you hit a one-hander or a two-hander.
What changes is which hip/shoulder is the pivot and how big the loop can be.
For a right-hander, your forehand loop rides around the right hip. The backhand loop rides around the left side / left hip.
Path, right-handed:
It's a mirror image of the forehand, not an exact copy. Forehand loop is more around and across; backhand loop is more up-down-around the front shoulder.
If you try to take the backhand straight back with no loop, you get exactly what you wrote for the forehand: no transition, energy is limited, and if you force it you get errors — usually late contact and a floating slice.
With two hands on the racket, the loop is much more compact, but it's still there.
Most good two-handers look "straight back" on TV, but in slow motion there's always a tiny drop and re-route. That's your small loop that allows transition from front to back.
So yes, mirrored. Forehand loops around the right hip, backhand loops around the left side. The size of the loop shrinks for the two-hander, but the front-to-back transition and the tip-to-ball prep you wrote down apply to both.
Do you hit your backhand one-handed or two-handed? I can map the exact loop path for your version.
Perfect. For a one-hander the loop is a mirrored, slightly more vertical version of what you described for the forehand. Same rules apply: tip to the ball, small continuous loop for front-to-back transition, contact well in front.
Here is how it maps for a right-handed one-handed backhand.
1. Prep: tip up and in front From ready, unit turn so your left shoulder points to the net. The racket comes up with the tip pointing up and a little to the back fence, and the hitting face slightly closed. The head stays in front of your chest, not buried behind you. That's your "racket top must be pointed toward the oncoming ball" cue, just on the backhand side.
2. The small figure-8 Instead of pulling straight back:
It's a mirror of the forehand loop. Forehand loops around the right hip and is more horizontal. Backhand loops around the left shoulder/left hip area and is more vertical, because you need that low-to-high brush for topspin with one hand.
3. Hip and shoulder drive Your notes say "Right Hip" for the forehand. For the one-hander, think left hip and left shoulder lead. You coil into your right back leg, then drive the left hip forward to open the chest. The arm is slung by that rotation, not muscled. The loop keeps the arm connected to the turn instead of disconnecting with a straight take-back.
4. Contact in front Because you never took the racket straight back behind you, the head is still in front of your front shoulder at contact. You meet the ball roughly a foot in front of your front foot, with the arm almost straight and the shoulder over the ball. That's the "contact will also be well in front" payoff you wrote.
Shadow with a pause check: Turn, get tip up. Slowly trace a small oval: tip up, head drops below imaginary ball, then up and through to finish over shoulder. If at any point the racket stops moving, the loop is too big or you pulled straight back.
Drop-and-catch: Hold the racket in the tip-up prep. Relax the wrist so the head drops by gravity. Catch it with your off hand at the bottom of the drop, then release into the swing. That drop is the loop. Keep it small, 12 to 18 inches of head travel.
Keep the loop small. The one-hander gets wild fast if the circle gets big. Think "tip to ball, small oval, drive left shoulder through."
Want me to sketch the forehand loop and the mirrored one-hander loop side by side so you can see the symmetry?
Here is how the loop maps for both sides. Same principle, mirrored pivot.
Loop rides around the right hip for a right-hander. Racket tip points to the incoming ball in front of your chest, then you let the head drop down and around in a small figure-8. The hip turns back to load, then fires forward and slings the arm through. That's the "unlimited energy" loop you wrote about.
Mirrored around the left side.
One-handed:
Two-handed:
In both cases the job of the small loop is exactly what you boxed on the right of your notes: it allows the racket to transition from front to back without stopping. That transition is what gives you adjustable power and keeps the racket in front of the body.
Want me to overlay your handwritten cues — "racket top pointed toward oncoming ball" and "contact well in front" — onto a one-hander vs two-hander side view?
Here is the side-view overlay with your exact cues from the notes:
What to look for
The loop is what makes those three positions possible without a pause. Straight back breaks the chain; the small figure-8 keeps it continuous for both FH and BH.
Want a simple shadow drill sequence you can do at home to feel the one-hander loop size?
Here is a simple at-home shadow sequence to groove the one-hander loop size and the front-to-back transition you wrote about.
Do it without a ball first, in front of a mirror or phone camera.
Set up Feet shoulder width, left shoulder to net, weight on right back foot. Hold the racket with a relaxed grip, off hand lightly on the throat.
Step 1: Prep check Turn and get the racket tip up and pointing to the side fence. The head is in front of your chest, not behind your back. The string bed is slightly closed, facing down a bit. Hold 1 second. This is your "racket top pointed toward oncoming ball" position.
Step 2: The small loop Relax the wrist and let the head drop down and a little forward in a tight C. The hand stays up, the head dips below where the ball would be. Trace a small oval about 12 to 18 inches tall. No pause at the bottom. If you hear a stop, the loop is too big.
Cue: think "down around the left hip" not "back."
Step 3: Drive and finish From the bottom of the drop, drive the left shoulder and left hip forward. Let the arm swing up and through, finishing with the hitting arm across the body and the tip pointing up. Contact point should be out in front of your front foot, arm almost straight.
Freeze at finish. Check: chest is open to the side fence, weight is on front foot, racket is over the shoulder.
Do 3 sets a day for a week. When it feels automatic, add a soft toss to yourself and keep the same small loop. The power will come from the hip turn slinging the arm, not from muscling the take-back.
