How to Use a Leg Press, Cybex Rower, and Dumbbells: The 5-Step Gym Floor Checklist I Run Every New Hire Through

Who this checklist is for (and why I built it)

If you run a gym floor, train new staff, or onboard members who've never touched a selectorized machine, this is for you. I'm not going to explain the biomechanics of every joint angle. I'm going to give you the exact five-step check I walk every new hire through before they're allowed to spot or coach on the floor.

Quick background: I've been handling gym equipment procurement and staff training for about eight years. In that time I've personally made—and documented—11 equipment-related mistakes that cost us roughly $16,000 in repairs, replacements, and one very avoidable liability claim. The worst one happened in my first year (2017), when a new hire loaded a plate-loaded leg press unevenly and a member tweaked their lower back. That was a $2,300 repair bill plus three weeks of dealing with insurance. Not fun.

Bottom line: this checklist exists so you don't repeat my errors. There are five steps. Each one has a specific checkpoint and one thing most people overlook.

Step 1: Cybex rower and water rower setup

Start with the rower because it's the machine people assume they already know how to use. They don't.

Checkpoint: Foot straps across the widest part of the foot, not the toes. Seat height adjusted so the handle sits at roughly lower-rib level when your arms are extended.

The mistake I see constantly: straps too loose. The rower becomes a leg-press machine with arms, and the user is basically doing quarter-reps with their quads while their lower back rounds. On a Cybex rowing machine, the damper setting matters too—most people leave it at 10 because "more resistance equals more workout." That's a red flag. A damper at 10 on a Cybex air rower is like cycling in your hardest gear uphill. You'll burn out in three minutes and your form will collapse.

A water rower behaves differently. The resistance responds instantly—there's no flywheel lag—so the catch needs to be quicker and smoother. If someone transitions from a Cybex air rower to a water rower and keeps the same rhythm, they'll feel like they're fighting the machine. That's normal. Tell them to slow the recovery phase by about 20%.

The overlooked part: handle height. On most Cybex rowers the handle chain has a sweet spot—pull to the lower ribs, not the sternum. Pulling too high turns it into a shrug exercise.

Step 2: Dumbbell lateral raises

This is the exercise that makes experienced lifters look like they've never been in a gym. The ego lift is real.

Checkpoint: Start with a weight you can control for 12 reps with a two-second pause at the top. If the dumbbells swing even slightly, drop down.

Three errors, in order of frequency:

1. Shrugging. The traps take over because the weight is too heavy. The cue is "push the elbows out, not the hands up." Physically touch the member's upper trap and say "keep this soft."
2. Elbows locked straight. A slight bend (maybe 10-15 degrees) keeps tension on the lateral delt instead of the joint.
3. Wrists breaking. The dumbbell should stay level—thumb side slightly higher is fine, but don't let the pinky side dip. That shifts load to the front delt and wrist extensors.

The overlooked part: breathing. People hold their breath at the top. Tell them to exhale on the way up. It sounds trivial until someone gets dizzy and drops a dumbbell on their foot (yes, I've seen it).

Step 3: Dumbbell squat to press

This one looks simple and isn't. The transition from squat to press is where form breaks down.

Checkpoint: The press starts as the legs finish extending—not after a pause at the top. If there's a visible stop between the squat and the press, the movement is two exercises stapled together, and the member is losing the core transfer that makes it useful.

Common errors:

• Leaning back during the press. The dumbbells drift behind the head, the ribcage flares, and the lower back takes over. Cue: "press slightly in front of your face, not straight up."
• Knees caving in at the bottom. Usually a hip mobility issue, not a strength issue. Reduce depth or load.
• Dumbbells clanking together at the top. That means the arms are too close. Widen the press path by a few inches.

The overlooked part: wrist position at the bottom. The dumbbells should be at shoulder height with palms facing forward or slightly inward—not rotated so far back that the wrists are extended under load. I learned this one the hard way after a member complained of wrist pain for two weeks. Looking back, I should have caught it during the initial walkthrough. At the time, I was focused on the squat depth and missed the wrist angle entirely.

Step 4: How to use a leg press machine

This is where new hires get nervous, because the leg press looks like it could fold someone in half if set up wrong. It can't—but the setup matters more than the weight.

Checkpoint: Feet shoulder-width apart, entire foot on the platform (heels not hanging off), knees tracking over the toes. Back and hips flat against the pad at all times.

The setup sequence I teach:

1. Adjust the back pad so the hips are comfortable but the lower back isn't rounded.
2. Set the safety stops before loading any weight. On most Cybex plate-loaded leg presses, that's the pin or lever near the carriage. If you skip this, you're asking for trouble.
3. Load plates evenly—same number on each side. I can't believe I have to write this, but after the 2017 incident, it goes on the checklist every time.
4. Member places feet, then releases the handles. Not the other way around.

The error that causes the most damage: going too deep. When the lower back rounds off the pad and the tailbone lifts, the lumbar spine is bearing load it shouldn't. Stop the descent when the thighs are roughly parallel to the platform—or slightly below if mobility allows, but never at the cost of the lower back lifting.

The overlooked part: the safety catches. Most members don't know they exist. Most new staff forget to show them. On a Cybex leg press, the safety catch is usually a spring-loaded lever near the handle. Demonstrate it once, have the member set it themselves, then move on.

Step 5: Cybex selectorized and plate-loaded equipment—general checks

This step applies to every Cybex strength machine on your floor, whether it's selectorized (pin-loaded) or plate-loaded.

Checkpoint: The weight pin is fully inserted. The seat and back pad are adjusted before the member sits down, not after. Plate-loaded machines have matching plates on both sides.

A few specifics:

• Selectorized machines: Pull the pin out, slide to the desired weight, push it in until it clicks. If it doesn't click, it's not seated. A partially inserted pin can slip mid-rep—I've seen it happen once and that was enough.
• Plate-loaded machines: Check that the plates are the same size and type on both sides. Mixing a 45 lb plate with a 35 lb plate creates an imbalance that most people won't notice until their shoulder does.
• Converging machines (like Cybex's converging chest press): the arms move inward as you press. Make sure the member's range of motion stops before the handles clank together—that's the machine telling you to reduce the load or shorten the range.

The overlooked part: seat position changes the exercise. On a Cybex shoulder press, raising the seat too high turns it into an incline press. On a leg extension, moving the back pad forward shifts the pivot point and stresses the knee. Show members where the adjustment numbers are and tell them to write down their settings. It takes 30 seconds and saves their joints.

Common errors I still see (and the fixes)

Even with the checklist, these three keep showing up:

• Loading before adjusting. The seat position is the first thing, not the last. If you adjust the seat with 200 lbs on the carriage, you're asking for a pinch point injury.
• Assuming "light weight" means "safe." Bad form with 10 lbs is still bad form. The lateral raise with 5 lb dumbbells and shrugged shoulders is worse than 15 lbs done correctly.
• Skipping the safety demonstration. On the leg press, the safety catch is the difference between a near-miss and an injury. Demonstrate it every single time.

One last thing—this was accurate as of early 2025, based on our equipment mix (mostly Cybex, some older plate-loaded units). If you're running different brands or newer models, verify the safety mechanisms before using this checklist verbatim. Machine design evolves, and what applies to a 2019 Cybex rower may not apply to a 2024 model. I learned that the annoying way when we swapped out two units and the damper settings didn't match the manual.
