Physical Therapist Creates 7 Tests That Expose Exactly Where You’re Weak (And Why Your Lower Back Seized Up on Test #2)

Everyone thinks they’re fit until they actually have to prove it.

Fitness influencer Jeff Cavaliere recently put together a comprehensive fitness test that challenges people of all ages to measure themselves against real standards—not feelings, not assumptions, but actual performance.

The question isn’t how others perform.

It’s how you would.

The Single Leg Wall Sit: Stability Under Fire

This test looks deceptively simple. Back flat against a wall, knee bent at 90 degrees, one leg lifted off the ground.

The goal? Hold it for 30 seconds on each leg.

Most of you watching right now are probably thinking, ‘Yeah, Jeff, that’s not a hard one. I could do that.’ However, 10 seconds in, you start to change your mind.

This isn’t just about quad strength. It tests hip stability, ankle control, and how well your body maintains position under fatigue.

Cavaliere uses this test often as a sports physical therapist to assess ACL injury risk. If holding your leg stable is difficult, imagine what happens when you’re running and that unstable leg moves repeatedly.

Wall Splat Test: Exposing Multiple Weaknesses at Once

Face a wall with toes about one to two inches away, slightly turned out. Arms go straight overhead.

Now squat down below parallel while keeping your chest up, head up, and without leaning on the wall. Hold for a second, then stand back up.

Sounds simple? It requires:

• Ankle mobility
• Hip mobility
• Thoracic spine extension
• Overhead shoulder mobility
• Pelvic and lower back control

Limited ankle mobility shows up immediately. Without enough dorsiflexion, people either cut depth short or lose position entirely.

Even when someone gets down, watch what happens overhead. Arms start to drift forward, usually from lack of thoracic spine mobility.

I got through it, but I’ll be honest, my lower back wasn’t too happy about it. It immediately seized up and started cramping like crazy because of how hard I was contracting it to keep the proper position of my pelvis.

Hand Release Push-Ups: Numbers Don’t Lie

Start face down, arms extended overhead. Bring hands back to just outside shoulders and press into a plank.

Lower chest all the way down. Lift hands briefly. Press back up to full extension.

Here are the standards:

• Men in their 40s: 40 unbroken reps
• Men in their 50s: 5-10% drop from that
• Men in their 60s and 70s: Another 7-12% decline per decade (still around 32 push-ups at 70)
• Men in their 20s and 30s: Closer to 50 reps
• Women in their 40s: 30 reps with same decline pattern

What separates people isn’t just who stops first—it’s how they stop. Hips sag, range of motion shortens, tempo changes, and core gives out before arms do.

Dead Arm Hang: Two Minutes of Truth

Grab a bar high enough so feet clear ground. Hands shoulder-width apart.

Depress shoulders slightly by pulling them away from ears. This engages scapula and provides stability.

Target time: 2 minutes for men in their 40s.

For every year after 40, deduct 1 second from expected time. That means a 70-year-old should hit about 1 minute 30 seconds.

Women in their 40s should aim for 1 minute 15 seconds, with the same 1-second yearly deduction.

This tests forearm endurance, scapular stability, overhead shoulder mobility, thoracic extension, and core control to prevent body wavering.

Most people don’t make it halfway. When they drop, it’s usually not hands that go first—it’s shoulders losing stable position and core losing stiffness.

Side Plank Leg Lift: Quality Over Quantity

Set up on your side, forearm flat, elbow directly under shoulder. Lift hips to create a straight line from shoulder to hip.

Raise top leg to about 45 degrees and hold.

Goal: 30 seconds on each side for both men and women, any age.

This tests lateral pillar strength, hip abductors (notoriously weak even when other lower body muscles are strong), and ability to keep trunk from collapsing.

People don’t usually fail by dropping all at once. They lose position slowly and they drift to a point where the finish doesn’t even look like the start.

Hips sag, shoulders sink, trunk rotates. Even Cavaliere’s top leg started coming forward to create balance his core should have been controlling.

Just because you made it 30 seconds doesn’t mean you passed. Quality matters as much as quantity.

Old Man Test: Balance Reveals Age Better Than Birthdays

Put on your sock and shoe while standing on one leg. No holding onto anything.

Foot stays off ground until shoe is on and tied. That’s the standard.

This tests single leg balance, ankle mobility, hip stability, and proprioception—your ability to sense position and make constant adjustments to stay upright.

It’s not about strength. It’s about control.

Extra touches, having to reset your body—it all counts. Either you hold position or you don’t.

Pull-Ups: The Great Equalizer

Full extension at bottom, chin clearly over bar at top. No kipping, no half reps, no shortcuts.

Standards:

• Men in their 40s: 15 unbroken reps
• Women in their 40s: 7 reps
• Fit men in their 70s: 7-10 reps

This measures strength relative to body weight. If you’re carrying excess weight without strength to move it, this exposes it immediately.

Look at how most people train. It’s heavily biased towards the front side, the show muscles, right? Chest, arms, shoulders, abs, and not nearly enough attention being paid to the backside muscles controlling your posture and your upper body pulling strength.

Add that over half the population sits above 25% body fat for men and 30% for women, where excess body fat becomes a penalty on every rep.

Natural strength decline is real—between 5-10% per decade. But even then, standards exist for a reason.

Standards Give Fitness Meaning

Not everyone will meet these standards right now. With a large percentage of populations overweight or obese, that’s simply reality.

But if everyone is fit, the word means nothing. Having a standard gives it value.

Every test points to something specific: a weakness to address, a limitation to improve, a gap to close.

When you improve, you don’t just get better at tests. You move better, feel better, and live better.

These tests represent muscular strength and endurance. Fitness also includes cardiorespiratory capacity and mental health—areas equally important to overall wellness.

Take these tests for what they are: a clear picture of where you stand today and, more importantly, a starting point for where you’re headed tomorrow.
