The Corps is considering planks as an alternative to crunches on the PFT

Marines have complained for ages that the crunches portion on the Physical Fitness Test, or PFT, is too easy, administratively hard to judge and easy to cheat on.

Now the Corps is looking at planks as an alternative.

In a December briefing for the Defense Advisory Committee on Women in the Services, the Corps said its Force Fitness Division, led by former Marine athlete of the year Col. Stephen Armes, was conducting a study on the use of planks as an alternative to crunches.

“The Marine Corps Force Fitness Division is currently testing and analyzing the use of planking as a possible measure of abdominal strength for the annual Physical Fitness Testing," Marine Corps Training and Education Command said in a statement. “Their testing remains ongoing.”

A plank is performed by holding the body in a tight formation, generally in a pushup-like position, and maintaining that form for a period of time. It is considered an isometric core exercise, as unlike crunches a plank does not involve contraction of the muscles during the workout.

Because the plank does not involve movement, there’s the possibility it could lead to fewer exercise related injuries during the PFT. The crunch portion of the PFT is often very sloppy as Marines rush to bang out over 100 crunches with poor form as they try to max their overall fitness scores.

“As a coach, I have my athletes do some ab variation at the end of every workout, but never does it include a ‘Marine Corps’ style situp,” said former Marine Sgt. Timminy Moore. “Those are not only not a good indicator of abdominal fitness, but it’s not good for lumbar or cervical spine.”

Since leaving the Corps in 2012, Moore has actively competed in powerlifting and CrossFit and has coached both sports for several years.

Brian Schilling, a professor of kinesiology and nutrition sciences at the University of Las Vegas, Nevada, said the Corps was wise to look at the plank as an alternative to crunches.

“For the most part, the muscles of the torso are ‘anti-motion;’ they work to stabilize the torso. This makes the plank a good representation of the real demands placed on the torso muscles,” Schilling said.

Schilling added that a 2012 study he co-authored in Military Medicine showed that the plank is “reliable,” and that over half of Navy sailors in the study wanted the plank to be part of the Navy fitness test.

Marines in a variety of fields say they would welcome the potential change, with some describing planks as a better core workout and a test easier for Marine leaders to administer.

One Marine Raider told Marine Corps Times that the plank was just an all-around better core workout, and from an administrative standpoint it is easier to judge proper form and harder to cheat on.

”It’s easier for me to look down a line and see everyone’s stomach off the ground than it is for me to count everyone’s crunches. So administratively it’s easier,” the Marine Raider said.

Male and female Marines between the ages of 21–40 have to knock out between 105–115 crunches depending on age and gender to maximize their score.

But it’s hard for scorers to accurately judge proper crunch form and the exercise is easily susceptible to cheating.

“For decades, people have just lied to help out their friends. With only a few proctors walking around to ensure the crunches were executed properly, it left a lot of room for cheating,” a recon Marine said.

Moore echoed those sentiments. “There’s so many ways to ‘game’ the ‘Marine situp’ to cheat the movement while still remaining in standards,” she said. “Planks are a good test of overall core stability; they test not just the main ab muscles, but also lats, rear delts, rhomboids, low back, quads, glutes, obliques; everything equally.”

Not everyone is sold on the idea that the plank will remove subjectivity from the test. It could be just as difficult to judge, leading to varying unfair standards across the Corps.

“Since there are some challenges with what is considered good form for both exercises in any case, so there will likely be no perfectly objective test,” Schilling said.

The Corps recently has flooded the force with nearly 600 Force Fitness Instructors, or FFIs, who have been charged with enforcing strict standards on the fitness tests.

“There was a lot of slop out there,” Armes said. Now there’s an FFI at the unit saying, “nope, that pullup doesn’t count … that crunch is not executed correctly.”

If the Corps decides to move to planks, those FFIs will help enforce proper form and standard with the new test.

Goodbye Curl-Ups: Navy Releases New PRT Rules for Planks and Rowing

The long-awaited rules for the new plank and rowing events on the Navy's fitness test are out, and officials say sailors should be preparing for the biggest changes in years.

Sailors cranking out as many curl-ups as possible in a 2-minute period will be a thing of the past starting in March. Instead, they'll need to hold a forearm plank for up to 3 minutes, 40 seconds, depending on age, to qualify for full marks on their Physical Readiness Test.

The tests, which were set to resume in January, have been postponed by several months due to the COVID-19 pandemic. The Navy will now hold just one Physical Fitness Assessment cycle in 2021, officials announced this week. It will run from March 15 to Sept. 15.

Scoring for the new plank event, which was announced in a service-wide message issued Wednesday, will be gender-neutral.

The switch from curl-ups to the plank, first announced by former Chief of Naval Operations Adm. John Richardson in May 2019, reflects an effort to focus on more functional movements, said Aviation Structural Mechanic Senior Chief Petty Officer Eric Anderson, with the Navy's Physical Readiness Program Office.

"The stabilization of your core when you're pulling on that line to moor the ship or carrying a box to put it in the storeroom, the stabilization of your core is where you're developing all that power from," Anderson told a small group of reporters. "So being able to do that and test that and make sure that our sailors have a strong core is going to help make us more ready and healthier."

The Navy's youngest personnel -- those between the ages of 17 and 19 -- will have the most rigorous plank requirement. They'll need to hold their bodies in a push-up-like position, with weight resting on their forearms, for 3 minutes, 40 seconds, to earn 100 points on the plank event. The minimum time that same group needs to hit to earn a satisfactory medium score is 90 seconds.

The time required to earn an outstanding score decreases by 5 seconds with each age group. Men and women between the ages of 25 and 29, for example, will be required to hold the plank for 3 minutes, 30 seconds, to earn 100 points, while sailors who are 30 to 34 will need to hit 3 minutes, 25 seconds, to earn the same score.

The plank is a safer exercise than curl-ups, Anderson said. Curl-ups, or sit-ups, which have been part of the PRT since the 1980s, can reaggravate lower-back injuries. The plank, he said, helps build muscles to prevent problems.

Also new on the test is an option to swap the 1.5-mile run for a 2-kilometer row using a rowing machine. That event, like the run, is timed, and scoring varies by age and gender.

Anderson said the plank scoring is gender-neutral to match the previous curl-ups requirement, which was the same for both men and women. Scores for the rowing option, like the run, will differ for men and women in every age bracket.

Men ages 20 to 24 at an altitude of less than 5,000 feet, for example, will need to complete the row within 7 minutes and 5 seconds to earn full marks on the event, with a time of 9 minutes and 25 seconds or more landing them in the probationary category. Women in the same age group at the same altitude will have between 8:05 and 10:35 to earn between an outstanding and satisfactory medium score.

Sailors completing the row at altitudes above 5,000 feet will get a bit more time.

Anderson said he's excited about the changes, particularly the plank, which will be required of everyone, because it's more relevant to what sailors do every day.

"Our goal with physical readiness is fitter, healthier sailors so we can accomplish the mission easier or be more successful at it," he said. "... Sailors are excited, and they're just ready to start."

Chief of Naval Personnel Vice Adm. John Nowell said both changes fit into the Navy's emphasis on physical, spiritual and mental well-being. Physical fitness is critical to the service's ability to meet operational challenges, he added.

"A great example of this are the Bonhomme Richard sailors and their shipmates on the San Diego waterfront who braved extreme heat and dangerous conditions over the course of several days of firefighting to save the ship," Nowell said, referring to a devastating July 12 fire aboard. "That was only possible by being fit and able to sustain long hours of firefighting."

What Counts and When

The Navy and other military services made the unprecedented move to waive or postpone several fitness requirements during the coronavirus pandemic. Barring any additional changes, though, the plank requirement and rowing option will go into effect with the 2021 PFA.

Nowell said the plank will be safer than curl-ups during the pandemic, since curl-ups required sailors to be face-to-face as they held down one another's feet during the event.

When the 2021 PRT resumes, sailors won't immediately fail if they don't pass the plank portion of the test.

"Because it's mandated, they would not be able to fail for the plank itself," Anderson said. On their next PRT, though, they must be prepared to perform the exercise to pass, he added.

The plank is the only portion of the test that sailors won't be required to pass in the 2021 PRT cycle. Since the row isn't mandated, sailors won't be offered a waiver or re-do if they fail.

Anderson suggests sailors not assume the row will be easier than the run without training for it first, because if they find they can't finish rowing in the allotted time, it's going to count against them.

The new PRT sequence will start with push-ups and move into the forearm plank event second, followed by the cardio option. That order, Anderson said, was based on feedback they got from hundreds of sailors in the fleet who tested the new events.

"We took that into account while we were doing the testing so that we could account for that fatigue," he said. "The plank standard ... is reflective of the fact that we know they did push-ups prior to doing the plank."

Similarly, he said, the scoring criteria for the cardio events consider that sailors just did the two other requirements before moving into the run or rowing portions of the test.

The Navy has released new videos and infographics that show the proper form and techniques for the new events. For the plank, sailors should place their feet no more than hip-width apart, keep their elbows aligned with their shoulders, and maintain their neck in a neutral position.

"It's actually going to help them keep the plank longer," Anderson said. "... [When] we're looking up trying to look at the clock, looking around the room, we're adding stressors to our upper body and to our back."

More than 500 sailors in Hawaii, Florida and Virginia helped set the scoring for the new events, Anderson said. The data collected during those studies, in which sailors were observed using rowing machines and doing forearm planks, was used by the Naval Health Research Center in San Diego to set the new scoring requirements.

The Navy will continue assessing data once sailors are performing the new test events, he added, to make sure the scores are reflective of an average person's performance.

The changes show the Navy listened to sailors' feedback on what they wanted to see on the PRT, Nowell said.

"I'm excited about this change," he said, "because the idea started with sailors and, overall, it's a better way to assess our fitness levels."
