Fueling the Army Fitness Test: The 72 Hours Before Test Day

How this article was sourced. Every factual, regulatory and dosing figure below is linked inline to its primary source — Army publications, the Human Performance Resources by CHAMP (HPRC), peer-reviewed position stands, or federal agency guidance. Where the evidence is weak or a figure could not be verified, this article says so instead of estimating.

This article has not been reviewed by a licensed clinician. It is general information, not medical advice, and it is not individualized to you. Talk to your physician, physician assistant, or a registered dietitian before starting any supplement, especially if you take prescription medication, have a medical condition, or are pregnant or nursing. Service members should additionally verify any ingredient against the DoD prohibited ingredients database before use.

If you are still reading fueling advice written around the ACFT, you are reading advice for a test that no longer exists. Per army.mil, the Army Fitness Test (AFT) became the official physical fitness test of record for all Soldiers on June 1, 2025, replacing the Army Combat Fitness Test (army.mil/aft). Most nutrition pages ranking for this topic have not been updated since.

This is what to eat, drink, and take in the 72 hours before a record AFT. Every number comes from the Army's own performance-nutrition arm or from a published position stand, linked inline.

What actually changed on 1 June 2025

The AFT is five events, not six. Per army.mil/aft:

1. 3 Repetition Maximum Deadlift (MDL) — "Deadlift the maximum weight possible three times."
2. Hand Release Push-Up — Arm Extension (HRP) — "Complete as many Hand-Release Push-ups as possible in two minutes."
3. Sprint-Drag-Carry (SDC) — "Conduct 5 x 50 meter shuttles for time."
4. Plank (PLK) — "Maintain a proper plank position for as long as possible."
5. Two-Mile Run (2MR) — "Run two miles for time on a measured, generally flat outdoor course."

The standing power throw is gone. What remains is dominated by repeated near-maximal effort (deadlift, sprint-drag-carry) and sustained aerobic output under isometric fatigue (plank, then a two-mile run).

Both run on muscle glycogen and on being hydrated. Neither runs on a supplement you bought on Tuesday.

Scoring reality: know which standard applies to you

Two standards exist, and they are not the same job:

Specialty	Standard
Combat specialties	One sex-neutral, age-normed standard requiring a total score of 350 with a minimum of 60 points per event
Combat-enabling specialties	Sex- and age-normed scoring requiring a total score of 300

Both figures are from army.mil/aft. The scoring tables were approved 15 May 2025, took effect 1 June 2025, run 0 to 100 points per event, and are split into ten age brackets from 17–21 through over 62. Pull your exact raw numbers from the official AFT Scoring Scales PDF, not from a calculator site. We do not reprint per-event raw values here: the tables are age- and column-specific and secondhand copies are frequently wrong.

One timeline note: army.mil states that new scoring standards for Soldiers in 21 combat military occupations took effect 1 January 2026 for the active component and 1 June 2026 for the Reserve and National Guard, with no administrative action taken regarding the AFT before 1 January 2026. Those grace periods are behind us. A record test in late 2026 counts.

72 hours out: carbohydrate, not novelty

Human Performance Resources by CHAMP (HPRC) guidance for road and foot marches is the closest thing the Army has to official fueling doctrine, and it transfers directly to test day. It recommends pre-event fueling of 1–4 grams of carbohydrate per kilogram of body weight, 1–4 hours prior to activity, and for the night before, a carb-rich meal because "fueling up on a carb-rich meal helps to maximize glycogen stores" (HPRC, Fueling for road or foot marches).

For an 80 kg Soldier that is 80 to 320 g of carbohydrate in the pre-event window. Wide range, on purpose: low end if you have a nervous stomach, high end if you tolerate food well and your test is later in the morning.

The most useful line on that HPRC page is the one nobody quotes: "Service Members should eat tried-and-true foods before and during the march. Test fueling options... as part of training... avoid experimenting with new foods or drinks the day of an event... to avoid intolerance and GI upset." If you have not run it in training, do not run it on test day.

What the three days should look like

Window	Do this	Why
T-72 to T-48 h	Normal training volume tapering down. Normal eating. Fluids at the daily military target: 96–144 oz/day for men, 64–96 oz/day for women.	HPRC daily fluid guidance (HPRC)
T-48 to T-24 h	Shift the plate toward rice, pasta, potatoes, bread, fruit. Keep protein steady. Cut fried food and very high-fibre volume.	Glycogen loading without GI risk
Night before	Carb-rich meal with lean protein and some fat. Nothing new. Alcohol: none.	HPRC night-before guidance
T-4 to T-2 h	14–22 oz of fluid and a familiar carbohydrate meal at 1–2 g/kg roughly an hour out; limit fibre, fat and protein at that meal.	HPRC pre-exercise fluid and meal guidance
T-60 min	Caffeine, if you use it. See dosing below.	ISSN caffeine position stand

Test-morning caffeine: dose it by bodyweight, not by scoop

The International Society of Sports Nutrition position stand on caffeine is unusually specific. Caffeine "has consistently been shown to improve exercise performance when consumed in doses of 3–6 mg/kg body mass," the minimal effective dose "may be as low as 2 mg/kg," and the most commonly used timing is 60 minutes pre-exercise. It also warns that "very high doses of caffeine (e.g. 9 mg/kg) are associated with a high incidence of side-effects and do not seem to be required to elicit an ergogenic effect" (ISSN caffeine position stand, 2021).

Run the arithmetic before you run the test. At 3–6 mg/kg that is 210–420 mg at 70 kg, 240–480 mg at 80 kg, 270–540 mg at 90 kg. HPRC's pre-march template suggests an optional 200 mg about an hour out — roughly a 16 oz coffee, or two pieces of caffeinated gum (HPRC). For most people that sits at the conservative end of the ISSN range, a sensible place to be on a graded event.

Two honest caveats. The ISSN stand notes that "adverse effects on sleep or feelings of anxiety following caffeine ingestion may be attributed to genetic variation," so one dose does not do the same thing to two people in the same squad. And more practically: a pre-workout that does not disclose caffeine in milligrams cannot be dosed by bodyweight. Our own PRE-MISSION CN03 ($40) lists caffeine in its ingredient panel but not the milligram amount, and our FIRST WATCH coffee pods ($19.90) carry no published per-pod figure either. If you want a specific mg/kg on test morning, use a source you can count and save the pre-workout for training days.

Lead with the label, not the benefits: PRE-MISSION carries a long contraindication list — not for anyone under 18, not for use if pregnant or nursing, and consult a physician first if you have hypertension, hypotension, heart, liver or thyroid disease, diabetes, arrhythmia, anxiety, depression, seizure disorder, or if you take any prescription drug.

Hydration windows around the two-mile run

HPRC states that "even as little as 2% dehydration is enough to affect both your physical and mental performance negatively," and gives session math you can actually execute (HPRC, Basic hydration strategies):

• Before: 14–22 oz of fluid 2–4 hours prior to exercise
• During: 16–32 oz every 60 minutes
• After: 20–24 oz for every pound lost
• Ceiling: "Avoid drinking more than 48 oz per hour, because this can contribute to low sodium levels in the blood, or hyponatremia"

An AFT is short, so the "before" number matters more than the "during" number. Front-load 14–22 oz in the 2–4 hour window, then sip, then stop. Drinking a quart in fifteen minutes is how people end up with a sloshing stomach on the plank. HPRC also notes that under an hour, "water is the best choice." A 32 oz bottle ($27.75) is useful mainly because it makes the math visible: one bottle is the per-hour ceiling.

Creatine: is loading before a record test smart?

The ISSN creatine position stand reports that a normal diet leaves muscle creatine stores "about 60–80% saturated," that supplementation raises muscle creatine and phosphocreatine "by 20–40%," and that after loading, "performance of high intensity and/or repetitive exercise is generally increased by 10–20%" (Kreider et al., JISSN 2017;14:18). Two protocols, both from that document:

• Fast: ~0.3 g/kg/day (about 5 g four times daily) for 5–7 days, then 3–5 g/day.
• Slow: 3–5 g/day, which "will increase muscle creatine stores over a 3–4 week period."

If your test is 72 hours out and you have never taken creatine, do not start now. Loading produces "a short-term fluid retention (e.g., about 0.5 – 1.0 L) that was generally proportional to the acute weight gain observed" (same source). Two pounds of water weight helps nothing in a two-mile run, and an unfamiliar four-doses-a-day protocol during test week is exactly the novelty HPRC tells you to avoid.

If your test is four to six weeks out, the slow protocol is the better play: 3–5 g/day of plain creatine monohydrate,* every day, no loading phase, no timing games. Our CN FORGE Creatine Monohydrate ($34) is unflavoured monohydrate with nothing else in the tub. Its listing describes the four-times-daily loading phase above; check the scoop weight on your own tub so you know what a 3–5 g maintenance dose looks like by volume.

On the dehydration rumour: the ISSN stand found "no evidence that creatine supplementation increases the anecdotally reported incidence of musculoskeletal injuries, dehydration, muscle cramping, gastrointestinal upset, renal dysfunction," and cites work in which 21.6 g/day for 7 days "did not increase the incidence of symptoms or compromise hydration status or thermoregulation in dehydrated (−2%), trained men exercising in the heat."

Protein after the test, and across the week

Protein does not change your score on Thursday. It changes whether the training block behind Thursday built anything. The ISSN protein position stand recommends a daily intake of 1.4–2.0 g/kg/day for most exercising individuals, per-dose amounts of 0.25 g/kg or 20–40 g containing 700–3,000 mg of leucine, distributed "every 3–4 h" (Jäger et al., JISSN 2017;14:20). HPRC's post-event guidance is a recovery meal within two hours containing 15–30 g of lean protein plus carbohydrate and fluid replacement (HPRC).

Real food first. A shake is convenience when the DFAC is closed. Operator Whey ($55) supplies 22 g of protein per serving from a whey isolate and concentrate blend, which supports normal post-exercise muscle recovery when it fills a gap in your daily total.* RELOAD BCAA ($36) delivers 5,000 mg of 2:1:1 branched-chain amino acids plus glutamine per serving. Be clear-eyed about the hierarchy: if you are already hitting 1.4–2.0 g/kg/day from food and whey, BCAAs are largely redundant, because a 20–40 g whole-protein serving already clears the position stand's leucine target.

What not to take, and how to check it yourself

Before you swallow anything in the week of a record test, run every ingredient through the DoD prohibited-ingredient database. Operation Supplement Safety states that "Service Members are prohibited from using any substance identified in this database as ingredients in dietary supplements," that the database "has been developed in accordance with Department of Defense Instruction (DoDI) 6130.06," and that it exists "to help Service Members identify substances to avoid when considering dietary supplement products" (OPSS, last updated 26 May 2026).

The instructions on that page are specific, and most people get them wrong:

• Search one ingredient at a time.
• Spell it exactly as it appears on the product label.
• Do not search by brand name.
• If you are unsure, use the OPSS "Ask the Expert" feature.

Two things follow. That database is a list of substances to avoid — it is not an approved-products list. No supplement is "military approved," ours included. There is no DoD endorsement and no OPSS endorsement of any brand. And a proprietary blend that hides individual ingredient amounts makes the OPSS workflow impossible to complete properly, which is a career risk rather than a marketing quirk. That is why our creatine tub has one ingredient in it.

The 72-hour plan, condensed

1. T-72 h: Last real session, light. Fluids at 96–144 oz (men) or 64–96 oz (women). Nothing new enters your body from here on.
2. T-48 h: Carbohydrate share of the plate goes up. Fibre and fried food go down. Sleep beats an extra workout.
3. T-24 h: Carb-rich dinner with lean protein. No alcohol. Caffeine dose decided and written down in milligrams.
4. T-4 to T-2 h: 14–22 oz fluid. Familiar carbohydrate meal, 1–2 g/kg, low fibre and low fat.
5. T-60 min: Caffeine at 3–6 mg/kg from a source whose dose you know.
6. T-0: Sip, do not chug. Stay under 48 oz in any hour.
7. Post: Within two hours, carbohydrate plus 15–30 g lean protein, and 20–24 oz of fluid per pound lost.

Fueling protects a score you already earned in the six months behind you. It cannot manufacture one. Train the deadlift and the two-mile run, then use the 72 hours to avoid shooting yourself in the foot.
