Strength Training: How NOT to do once-a-week strength training

Strength Training: The Devil Is in the Details

Outside Magazine, to their everlasting credit, ran an article entitled The Data Behind a Once-a-Week Strength Routine. The subtitle was intriguing: a new study had tracked the progression of thousands of people following an ultra-minimalist training plan. As I read into the protocols and tools used, I thought my head would explode.

A single thought kept pushing its way to the forefront of my consciousness: if I were looking to purposefully sabotage results from a long study on the benefits of once-a-week strength training, what would I do?

First off, I would select exercise machines over barbells, dumbbells, and free-weight equipment. If the goal is lesser real-world strength transfer, choose tools that eliminate the third dimension of tension. The third dimension of tension is the need to control side-to-side movement, sway, tilt and deviation from the optimal motor pathway.

Machines have frozen grooves that allow the trainee to allot nearly all available strength to either pushing or pulling. Since there is less need to control sway, there is less need for the stabilizers to fire the way they must when a lifter has a wayward barbell, dumbbells, or plates moving through space.

USA made weight plates for deadlifts, squats, and bench press.

What the Once-a-Week Study Actually Showed

The Outside article summarized a large Fit20 dataset. The protocol involved one workout per week, typically six exercises performed on Nautilus One machines: chest press, pulldown, leg press, abdominal flexion, back extension, and either hip adduction or abduction.

Each exercise was performed for one set to momentary failure after roughly four to six repetitions. The repetitions were performed extremely slowly: about ten seconds up and ten seconds down. Rest between exercises was short. Loads were adjusted over time so the trainee would continue reaching failure inside the prescribed rep range.

At the time Outside wrote about the study, the paper was still a preprint. It has since appeared in peer-reviewed form. The dataset is impressive: 14,690 participants, records extending up to approximately 6.8 years, one weekly session, one set to momentary failure across six machine exercises.

That matters. We are not talking about six guys in a garage for three weeks. The study shows that a highly standardized, ultra-minimal, machine-based, once-weekly protocol can produce measurable machine-load improvement in a large general population over time.

Good. That is useful. That is not the same thing as proving that this is optimal strength training, performance training, bodybuilding training, powerlifting training, or athletic preparation.

Public-Health Strength Is Not Powerlifting Strength

This is the distinction that keeps getting lost.

From a public-health perspective, a minimal effective dose can be a good thing. Getting previously untrained or undertrained adults to perform some kind of resistance work consistently is a victory. The person who was doing nothing and now trains once per week under supervision is better off than the person still doing nothing.

But do not confuse a public-health minimum with a performance optimum.

The once-week machine protocol may increase the exact loads used on the exact machines used in the exact protocol. That is task-specific progress. It does not automatically mean the person has become meaningfully stronger in the squat, deadlift, press, clean, loaded carry, sport movement, or real-world strength task.

When a trainee improves on a machine chest press, the trainee has improved on a machine chest press. That is not nothing. It is also not the same as becoming strong under a free barbell.

Outside’s own article made the important distinction: the dataset offers insight into minimal effective dose for general health, but it should not be confused with what serious athletes need to optimize performance.

Machines, Free Weights, and the Missing Third Dimension

I am not saying machines are useless. That would be too broad. Good machines can build muscle. Good machines can provide safe assistance work. Good machines can help beginners, older trainees, injured lifters, and bodybuilders target a muscle without asking the entire organism to solve a balance problem.

But machines and free weights do not ask the same question.

A machine asks: can you push or pull along this predetermined path?

A barbell asks: can you create force, control the implement, stabilize your body, maintain posture, direct the load, solve balance, and finish the lift without the tool drifting into disaster?

That difference is critical. If your goal is better machine performance, use the machine. If your goal is real-world barbell strength, athletic strength, powerlifting strength, or strength that demands whole-body control, then free weights must be central.

Again, from a saboteur perspective, after I pick the narrowest tool, I then select the lamest possible protocol.

Super-Slow Reps, Limited ROM, and Tiny Payloads

If you take ten seconds to lower a rep and ten seconds to raise a poundage, that equates to twenty seconds per repetition and two full minutes to complete a six-rep set.

As a saboteur seeking to further ruin transferable strength results, I would insist on partial reps, never locking out, never settling, never owning the full range of motion. Super-slow repetitions and excruciatingly long sets compromise poundage-handling ability to an unacceptable degree if the goal is serious strength.

Slow can be useful. Control is useful. Tension is useful. But very slow reps with tiny payloads, on machines, using abbreviated movement, are not the path to explosive, usable, high-end strength.

Question: someone please explain how moving tiny payloads very slowly for two minutes, using a limited ROM in six fixed-path exercises, makes you stronger in any broad, transferable sense?

I guess you use Orwellian double-speak and create a new definition of stronger. In this instance “stronger” is conveniently defined as improving a trainee’s initial readings on the same machines, inside the same flawed little universe.

Another great way to increase “strength” when using a purposefully reduced range of motion is to shorten your already shortened range of motion on report-card day. Cut an inch or two off the top of a partial rep, then cut an inch or two off the bottom of each already shortened rep stroke. This shortening of the already shortened rep stroke will be barely detectable to the human eye and will result in vastly improved leverage.

Who is going to notice? Are they measuring the ROM on every rep?

In the real world, slow-motion, two-minute-long sets using pee-wee poundage produce little transferable performance strength.

Task-Specific Progress Is Not the Same as Transferable Strength

What possible benefit could be had doing these bizarre drills on antiquated machines, using purposefully shortened ROM, each non-locking rep different than the one before it and the one after it? This protocol strengthens you how? For what?

The only thing you improve with certainty is the ability to register improvement within the system they created. Improvements inside a fatally narrow strength system are narrow improvements.

That is the part that drives me crazy.

Instead of asking, “Did the participant improve the load on this exact machine?” ask better questions:

• Did the trainee become stronger in free-weight squats, presses, rows, pulls, or carries?
• Did the trainee improve full-range strength?
• Did stabilizers and balance improve?
• Did athletic power improve?
• Did strength transfer outside the six machines?
• Did physique change in a meaningful way?
• Did the trainee gain options when the protocol stopped working?

In another head-scratcher, nobody seems to have figured out that resistance programs, even effective ones, need periodic rotation. If you never change the six exercises, never change how you do them, never alter the frequency, never alter the stress, stagnation is a foregone conclusion.

The Real Once-a-Week Strength Training Question

Here is the inconvenient truth: a machine allows for a single frozen-groove exercise. A barbell has a hundred exercise possibilities and variations.

The bad news from the super-slow study was that the protocol eventually stopped working as well, or at least became less effective. Wow. A resistance-training program that stops working. Thank God for science pointing that out.

The real question is not whether one weekly strength session can do something. Of course it can.

The real question is: what kind of once-a-week strength session are we talking about?

A once-weekly assault built around squats, presses, deadlifts, rows, chins, carries, intelligent assistance work, progressive loading, full range of motion, and rotating templates is not the same animal as a 20-minute slow-motion machine circuit.

One can maintain or improve general machine strength inside a public-health framework. The other can change physiques, build real strength, create athletic carryover, and keep a serious trainee progressing when life only permits one weekly session.

You can only switch to another program if you have another program.

In the case of the “strength gains” associated with the super-slow, limited-ROM, extended-set machine protocol, the progress is, without a shred of doubt, highly task-specific. Meanwhile, real-deal once-a-week strength training, the type we practice, the type that can skyrocket real-world strength and radically change physiques, is totally ignored.

My head is exploding.

Equipment Notes for Real Once-a-Week Strength Training

Real once-a-week strength training is not equipment complicated. It is effort complicated. It requires tools that allow hard, measurable, repeatable work.

For a barbell-centered session, lifters and facilities can compare Olympic weightlifting bars, weight plates, and serious bars such as the IRON COMPANY Iron Cowboy Powerlifting Bar. For Olympic-style pulls, power work, or dynamic training, TKO solid rubber bumper plate sets can support appropriate loading when used on the right surface.

For dumbbell work, dumbbells and products such as IRON COMPANY urethane hex dumbbells can support presses, rows, carries, and assistance work. Machine and cable work can still have a place when selected intelligently; plate-loaded leverage equipment, selectorized gym equipment, and a cable unit such as the Legend Fitness SelectEDGE Cable Crossover Plus are tools, not enemies.

The equipment does not create results. The lifter, the template, the load, the range of motion, the progression, and the intent create results.

Safety Note for Minimal-Dose and High-Intensity Strength Training

Minimal-dose strength training can help many people start and stay consistent. High-intensity once-a-week strength training can also work when the athlete is skilled, recovered, and using an intelligent template. These are not the same thing.

Training to momentary failure on machines, training heavy with free weights, using slow tempos, emphasizing full range of motion, and compressing serious work into one weekly session all require judgment. Beginners, older trainees, deconditioned people, and lifters returning after injury should start conservatively and seek qualified coaching when needed.

Use proper setup, full attention, appropriate loading, spotters or safeties when needed, and honest technique standards. Stop for sharp pain, dizziness, numbness, loss of position, unusual shortness of breath, or repeated technical breakdown.
