The Basic Endurance Drill (BED) is a military calisthenics protocol used in U.S. Air Force Special Warfare prep, Marine Corps OCS conditioning, and Special Operations selection courses to build raw muscular endurance — typically 5 to 8 rounds of pull-ups, push-ups, sit-ups, dips, and squats performed at near-maximum reps with 60 to 90 seconds rest between rounds. Total session time runs 25 to 45 minutes. Total volume is brutal — often 200+ push-ups, 100+ pull-ups, and 200+ squats in a single workout. The drill is designed not to build strength or hypertrophy but to harden you against fatigue under repeated bodyweight load — the exact demand of Special Warfare candidate selection.
This guide explains what the Basic Endurance Drill actually is, the exercise menu used across services, the standard rep schemes, a scaled version civilians can run today, the programming logic (frequency, progression, tapering), and how it compares to civilian protocols like CrossFit MetCons, HIIT circuits, and bodybuilding endurance work.
What is the Basic Endurance Drill?
The Basic Endurance Drill is not one rigid workout — it’s a category of structured calisthenics circuit used across the U.S. military to build the muscular endurance needed for sustained operational tasks: rucking with load, climbing fast roping, repeated obstacle traversal, and the volume-heavy PT tests used in selection (Air Force Special Warfare Operator Enlistment Course, Marine Corps OCS, Ranger School pre-selection).
- 5 to 8 rounds of upper-body and lower-body bodyweight exercises
- 10 to 25 reps per exercise, typically near max sustainable pace
- 60 to 120 seconds rest between rounds (sometimes EMOM-style)
- 4 to 8 exercises per round, alternating push/pull and upper/lower
- 25 to 45 minutes total session time
The drill produces high local muscular fatigue while maintaining reasonable cardiovascular load. Unlike CrossFit “for time” workouts, the BED prioritizes consistent rep quality over pure speed. Form breakdown is the failure point — not clock time.
The standard exercise menu
- Pull-ups — overhand grip, dead-hang start, chin over bar
- Push-ups — full range of motion, chest to floor, arms locked at top
- Sit-ups — military style, hands on temples or crossed at chest, full range
- Bodyweight squats — hips below knee crease, full lockout
- Dips — parallel bars, full extension at top, shoulder below elbow at bottom
- Burpees — chest-to-deck, full jump and clap overhead
- Mountain climbers — alternating, fast tempo
- Flutter kicks — Marine-style, 6-inches, both legs counted as one rep
Air Force Special Warfare candidates typically face the first six. Marine Corps prep adds flutter kicks and 8-count bodybuilders. The point of the limited menu is repeatability and standards — every rep is tested to the same form criteria, every workout, every candidate.
Standard military protocol
| Round | Exercise | Reps | Notes |
|---|---|---|---|
| 1 | Pull-ups | 10 | Strict, dead hang |
| 1 | Push-ups | 25 | Full ROM |
| 1 | Sit-ups | 25 | Hands on temples |
| 1 | Squats | 25 | Hip below knee |
| 1 | Dips | 15 | Parallel bars |
| Rest 90 seconds. Repeat for 5 to 8 total rounds. | |||
Total volume at 6 rounds: 60 pull-ups, 150 push-ups, 150 sit-ups, 150 squats, 90 dips. Session time: roughly 35 minutes including rest.
A scaled version for civilians
- Round 1–3: 5 pull-ups, 15 push-ups, 20 sit-ups, 20 squats, 8 dips
- Rest: 90 seconds between rounds
- Total session: 25 to 30 minutes
- Frequency: 2x per week, with strength training and running on other days
- Progression: add 1 round every 2 weeks, then increase reps per round
If you’re newer to calisthenics, substitute assisted pull-ups (band or jumping negatives), knee push-ups, and bench dips. Start at 3 rounds, rest 2 minutes, build over 6 to 8 weeks. Our beginner calisthenics routine covers prerequisite movement quality.
Programming the BED into a real schedule
- 2x per week BED sessions (e.g., Tuesday and Friday)
- 2x per week dedicated strength work (weighted pull-ups, weighted dips, squats, deadlifts)
- 2x per week running or rucking (one tempo run, one long ruck or distance run)
- 1 full rest day per week — non-negotiable
This split alternates the major fatigue systems. The BED hits muscular endurance; strength sessions build the absolute capacity that lets endurance be productive; running develops cardiovascular base. For specific selection prep, see our special forces calisthenics and ACFT calisthenics prep guides.
8-week progression plan
| Week | Rounds | Rest | Sessions/wk |
|---|---|---|---|
| 1–2 | 3 | 120 sec | 2 |
| 3–4 | 4 | 90 sec | 2 |
| 5–6 | 5 | 90 sec | 2 |
| 7 | 6 | 75 sec | 2 |
| 8 | 6 (test) | 60 sec | 1 + retest |
Track total reps each session. Progression is real when you complete more rounds at the same rep counts, OR more reps per exercise at the same round count.
BED vs CrossFit, HIIT, and bodybuilding endurance
| Protocol | Primary goal | Tempo | Time | Best for |
|---|---|---|---|---|
| Basic Endurance Drill | Muscular endurance | Sustained near-max | 25–45 min | Selection prep, military, tactical |
| CrossFit MetCon | Mixed metabolic | For time | 5–25 min | General fitness |
| HIIT | Cardiovascular | Interval bursts | 15–25 min | Conditioning, fat loss |
| Bodybuilding endurance | Local muscle endurance | Set-based | 45–75 min | Hypertrophy + endurance |
5 common mistakes
- 1. Running it daily. Too high-fatigue. 2 sessions per week is the proven dose.
- 2. Counting partial reps. Selection cadre don’t count partial pull-ups, push-ups that don’t reach the floor, or squats above parallel.
- 3. Skipping the strength work. Endurance volume without absolute strength capacity caps your rep ceiling.
- 4. Ignoring sleep and food. 8+ rounds demands 2,800–3,500 kcal/day with 1 g protein per lb bodyweight.
- 5. Rushing the progression. Jumping from 3 to 8 rounds in 2 weeks tears down more than it builds.
Basic Endurance Drill FAQ
What does Basic Endurance Drill mean in the military?
It refers to a structured calisthenics circuit used in selection prep across U.S. military Special Operations communities — Air Force Pararescue, Combat Control, Marine Corps OCS, Army Ranger Assessment. Standard structure: 5 to 8 rounds of pull-ups, push-ups, sit-ups, squats, and dips with short rest periods.
How often should I do the Basic Endurance Drill?
Twice per week is the proven dose for adaptation without breakdown. Pair with 2 strength sessions and 2 running or rucking sessions per week, plus 1 full rest day.
Can civilians do the BED safely?
Yes — at scaled volume. Start with 3 rounds at 50–60% of your max reps per exercise, with 2 minutes rest. Build over 6 to 8 weeks. Avoid jumping straight into selection-volume sessions if you can’t already do 10+ pull-ups, 30+ push-ups, and 30+ squats with strict form.
What’s a good BED workout for beginners?
3 rounds of: 3 pull-ups (or assisted), 10 push-ups, 15 sit-ups, 15 squats, 5 bench dips. Rest 2 minutes between rounds. Run 2x per week for 6 weeks before increasing rounds. Pair with our how to get better at pull-ups and push-up progression guides.
Does the BED build muscle?
It builds endurance more than mass. The high-rep, low-rest format favors muscular endurance over hypertrophy. For mass gain, pair the BED with separate strength sessions (weighted pull-ups, dips, squats at 5–8 reps with longer rest).
BED vs Murph — which is harder?
Murph is a single benchmark workout (1 mile run, 100 pull-ups, 200 push-ups, 300 squats, 1 mile run); the BED is a repeatable training protocol. Murph is more brutal in a single session; the BED is more sustainable for ongoing adaptation.
The bottom line: the Basic Endurance Drill is the proven calisthenics endurance protocol used across U.S. military Special Operations selection prep — 5 to 8 rounds of pull-ups, push-ups, sit-ups, squats, and dips with short rest. Run it twice per week, build over 8 weeks, and pair with strength and running work.
