She Tore Her ACL on a Dive Boat. Then She Did the Opposite of What Most People Do.
/Liza's weekends belong to the water.
Catalina, mostly. Kelp forests, a new kind of fish every time, the whole thing different from one dive to the next. She'll tell you it's one of the best places to dive in the country, and she'd know — she goes as often as she can. Galapagos is on the list. Indonesia too.
What she doesn't lead with is that she was terrified the first ten times she went under. She just knew she loved the ocean enough to keep taking classes until the fear ran out.
Hold onto that. It matters later.
The Injury Nobody Expects
She was on a boat. A wave came through. Her equipment was heavy, her knee twisted, and she heard it snap.
"I was like, oh, this is not good."
She was on vacation, so she kept diving. When she got home, she got the MRI, and the orthopedic doctor gave her the sentence that reorganizes a person's next year: you tore your ACL.
Surgery went on the calendar.
And this is where the story usually goes one of two ways. Most people wait. They rest, they protect the knee, they stay off it, and they show up on surgery day weaker than they were the moment they got hurt. It feels like the responsible thing to do. It isn't.
Liza's husband was already coming to HealthFit for his shoulder. He'd been telling her about it — the staff, the place, the fact that his shoulder was actually getting better. His exact recommendation, as she remembers it: "Oh my gosh, you just got to go there."
So she came in before surgery instead of after.
What Prehab Actually Is
Prehab is exactly what it sounds like: rehab that happens before the operation.
For an ACL, that means about four to six weeks of restoring range of motion, calming the swelling down, and — most importantly — building the muscle around the knee back up. Quads especially. The goal is simple to say and harder to do: walk into the operating room stronger than the day you tore it.
Liza did about a month to a month and a half of it.
"We just worked on getting my muscles being stronger, going into surgery stronger than what I was before. And I think that really made a difference."
She's right, and there's data behind the instinct.
The number worth knowing
A comparative study published in the American Journal of Sports Medicine compared two large ACL cohorts — the Delaware-Oslo cohort, which does extended pre-operative rehabilitation as standard, against the MOON cohort, which does not. Two years after surgery, 72% of the extended-prehab patients had returned to their pre-injury sport, compared with 63% of those who hadn't. The prehab group also showed significant and clinically meaningful advantages in knee function scores after adjusting for baseline.
Two years out. From work done before the scalpel ever touched the knee.
That's the part people miss. Surgery reconstructs a ligament. It doesn't hand you back your quad, your balance, your confidence, or the ten years of movement habits your body had before you got hurt. Whatever strength you bring into surgery is the platform you rebuild from afterward. Bring less, and you spend the first months of rehab digging back to where you already were.
Source, Cause, Stack. The SOURCE is the torn ligament. The CAUSE is everything that quietly erodes from the moment of injury — strength, motor control, tissue quality, confidence. The STACK is what we deploy against both, together, from Day 1: hands-on work, exercise, and regenerative tools where they're indicated. Not one after another. All of it, in parallel.
Three Months Out: Relearning Before Loading
Liza started training with Coach Allister three months after her reconstruction.
"We started more just learning how to do the movements. Obviously not going as strong."
That sentence deserves more respect than it usually gets. Three months post-ACL is not a strength phase. It's a pattern phase. The knee can bend and bear weight, but the way the body organizes a squat, a step-down, a hinge — that has to be rebuilt deliberately, because the body has spent months solving those problems by avoiding the injured side.
Load a bad pattern and you get a stronger bad pattern.
So the early work is quality first. Then, over the following months, load gets added on top of a movement that's actually worth loading.
"Through the months now we're just adding all these different exercises. Stuff that I didn't think I would ever do. There's just been a lot of growth in the past seven months."
Ten Months Out: What Changed
Ten months since surgery. Seven months of training.
Here's her list, in her words:
- "I have gotten so much stronger."
- "My confidence has gone up."
- "More energy."
- "I have no body pain anymore."
And then the line that we keep coming back to:
"I thought I was getting older. But I just needed to work out."
That one deserves its own paragraph, because it's the quiet story underneath half the people who walk into our clinic. The stiffness, the low energy, the aches that show up without a clear cause — a lot of people file all of it under age, because age is the explanation that requires nothing of you. Sometimes age really is the driver. Very often it's disuse wearing an age costume.
Liza is ten months removed from a reconstructed ACL and she has less body pain than she did before she got hurt. Not because she got younger. Because she got stronger.
"I Can Do Hard Things"
The best part of the interview has nothing to do with her knee.
"He pushes me to lift harder, or do things that maybe I thought I couldn't do. And I do do them. And now when I find myself in situations where things are difficult — let's say scuba diving, I have this heavy equipment, I'm walking up a hill — I'm just thinking, I can do hard things, because I do this at the gym."
That's the whole return on investment, right there.
Strength training gives you a repeatable, honest experience of doing something hard and finishing it. Your nervous system keeps that receipt. Then a hill shows up with forty pounds of dive gear on your back, and instead of running the math on whether you can make it, you just walk up the hill.
Remember the diver who was terrified her first ten times under? Same person, same pattern. She does the hard thing enough times that it stops being the hard thing.
The Two Things That Made It Stick
Ask Liza what actually made the difference and she doesn't say a machine or an exercise. She says two words.
Accountability. "Having someone to see your progress and cheer you along the way. I think that's major."
Structure. "I work out here, and then when I go to the gym, I know what I need to do, what I need to work on, and then we talk about it."
This is why one-on-one time matters more than equipment. Anyone can buy a squat rack. Nobody buys the person who noticed your left side was lagging in week four and adjusted the plan.
The Habit Stack: One Thing at a Time
The knee work opened a door to everything else — sleep, water, nutrition. But she didn't do it all at once, and that's the part worth stealing.
Her order:
1. Sleep habits first.
2. Then consistency — actually showing up to train.
3. Then water.
4. Then breakfast.
5. Then, a few weeks ago, lunch.
"By taking it one step at a time, it doesn't feel overwhelming."
That's the most practical advice in the entire interview, and it costs nothing. Most people fail their health overhaul in week two because they tried to change six things on a Monday. Liza changed one thing, let it become automatic, then added the next. Ten months later the sum total is enormous, and she never once had to white-knuckle it.
If You Have a Surgery Date on the Calendar
Here's what we'd want you to take from Liza's story:
Don't wait. The weeks between diagnosis and surgery are not dead time. They're the highest-leverage weeks in your entire recovery, and almost nobody uses them.
Strong going in means strong coming out. You cannot out-rehab a body you let deconditioned for six weeks.
Rehab isn't over when you're cleared. Cleared means the tissue healed. It doesn't mean you're strong, and it definitely doesn't mean you're confident. Liza's biggest gains happened between months three and ten — long after most people stop.
Age is a suspect, not a verdict. Before you accept that this is just how your body is now, find out what it does with three months of real training.
Liza put it this way: "I don't feel limited by my age, my injury, or just nothing."
She's planning Galapagos.

Liza was terrified the first ten times she went underwater. She kept going until it turned into the thing she loves most. A torn ACL was never going to be the thing that ended that — but only because she treated the six weeks before surgery like they counted.
They counted.
