Why prehab beats rehab
Prehab is the practice of strengthening your weak links before they become injuries. Rehab is fixing them after they break. Prehab is dramatically more efficient.
This 8-exercise routine takes 15 minutes, requires no equipment beyond your bodyweight, and targets the exact weak links that cause rucking injuries: weak ankles, poor arch stability, weak quads, weak glutes, unstable hips, weak core, rounded shoulders, and poor shoulder mobility.
If you do this routine 2 to 3 times per week, you'll address most of the common weak links that lead to injury in new ruckers. You can do it as a warm-up before rucking, as a standalone session on rest days, or split between multiple days depending on your schedule.
Prehab is most effective when paired with proper footwear. Shoes that support your arches and ankles amplify what your prehab work achieves. Check out our Salomon XA Pro 3D or explore more options in our best rucking shoes by terrain guide to find footwear that matches your rucking environment.
Most people who skip prehab because they're "too busy" end up injured by month 3 or 4, at which point they wish they'd invested 45 minutes per week in prevention. This routine is insurance.
The 8 exercises
1. Calf raises (3×15)
Calf raises build strength and endurance in your calves and the intrinsic muscles of your foot. Your calves are the engines of walking, and under loaded conditions, they need to be strong.
Stand on flat ground, rise up onto your toes, pause briefly at the top, then lower back down under control. Do 3 sets of 15 reps at a slow, deliberate pace - speed defeats the purpose here.
Stand on the edge of a step so your heel can go below the level of your toes. Rise up, then lower down below the step level. This increases the range of motion and targets the muscle more completely. Do 3 sets of 12 to 15.
Perform single-leg calf raises on the edge of a step. This dramatically increases difficulty and builds unilateral strength and balance. Do 3 sets of 8 to 10 per leg.
Do these slowly - there's no benefit to fast calf raises. A 2-second rise, 2-second pause at the top, and 2-second lower is ideal.
2. Bodyweight squats (3×12)
Squats build quad strength (essential for knee health) and glute activation. Your quads and glutes work together under load, and weak quads lead to knee pain and lower back strain.
Stand with feet shoulder-width apart, lower your butt back and down until your thighs are roughly parallel to the ground. Your chest should stay upright and your weight should be on your heels. Push back up to standing. Do 3 sets of 12.
Lower further into a deep squat - ass to grass if you have the mobility. The deeper you go, the more you challenge your quads and hips. Full-range squats are worth the extra effort. Do 3 sets of 12.
Hold a weight at your chest (goblet squat) or add a pause at the bottom (hold for 2-3 seconds before rising). Either variation increases difficulty significantly.
Don't rush squats. Full range of motion matters more than reps. If you can only do 8 full-range squats, do 3 sets of 8. Partial reps are less valuable.
3. Glute bridges (3×12)
This is the single most important exercise in this routine. Weak glutes are the root cause of most knee pain, lower back strain, and hip tightness in ruckers. Your glutes are the prime movers for loaded walking, and they need to be strong and activated.
Lie on your back with knees bent and feet flat on the ground, hip-width apart. Drive through your heels, extend your hips, and lift your butt off the ground until your body forms a straight line from knees to shoulders. Squeeze your glutes hard at the top for a 2-second pause. Lower back down. Do 3 sets of 12.
At the top position, hold for 2 to 3 seconds and really focus on squeezing your glutes. The glute squeeze matters more than the height. Some people do single-leg glute bridges: lift one foot off the ground while the other leg does the work. Do 3 sets of 10 to 12 per leg.
Hold a barbell or heavy weight on your hips. Or do single-leg glute bridges and hold a weight. This adds significant resistance.
The key cue: squeeze your glutes at the top. This muscle activation is what matters. Many people perform glute bridges but fail to actually activate their glutes - they just lift their hips. Focus on the squeeze.
4. Bird dogs (3×8 each side)
Bird dogs develop core stability, spinal erector endurance, and anti-rotation strength. This is crucial because your lower back stabilizes load during rucking, and weak stabilizers lead to pain.
On your hands and knees, extend one arm forward and the opposite leg backward until they're in line with your body. Hold for 1 second, return to starting position. Alternate sides. Do 3 sets of 8 each side.
Hold the position for 2 to 3 seconds. Move slowly and deliberately. Focus on not rotating - your body should stay square to the ground throughout.
Add a 2 to 3-second hold at full extension to increase the stability demand, or loop a resistance band around your extended leg for added resistance. Keep your hips perfectly level throughout - any rotation means the load is too much.
Bird dogs are about quality and control, not speed. A 1-second hold that's perfectly stable is worth more than a fast repetition that lets your hips rotate.
5. Dead bugs (3×8 each side)
Dead bugs develop anti-extension core strength. Your lower back is under constant load during rucking, and it needs to resist extending and rounding. Dead bugs directly train this pattern.
Lie on your back with arms extended toward the ceiling and knees bent at 90 degrees (thighs perpendicular to ground, shins parallel to ground). Slowly lower one arm overhead while extending the opposite leg until it's nearly straight. Return to starting position. Alternate sides. Do 3 sets of 8 each side.
Make the movement slower. A 2-second lower, 1-second pause, and 2-second return makes this significantly more challenging.
Extend both opposite limbs at the same time instead of alternating - this doubles the anti-extension demand on your core. Alternatively, strap on ankle weights to increase resistance without changing the movement pattern.
The critical rule: your lower back must stay flat against the ground throughout. If your lower back arches up, you're extending too far. Stop before that point. This exercise is about training the core to resist that extension.
6. Banded clamshells (3×12 each side)
Clamshells strengthen your hip abductors (glute medius and minimus) and external rotators. These muscles stabilize your hips under load and prevent your knees from caving inward (valgus collapse). Weak hip abductors are the primary cause of IT band syndrome and lateral knee pain.
Lie on your side with knees bent at 90 degrees and your feet together. Keep your feet touching while you raise your top knee toward the ceiling. The movement comes from your hip; your feet stay together and your bottom knee stays on the ground. Do 3 sets of 12 each side.
Loop a light resistance band around your thighs just above your knees. The band adds tension throughout the full range of motion, forcing your hip abductors to work harder on every rep and making the muscle engagement much more deliberate.
Do banded walks instead - with a band looped around your thighs, walk sideways in a quarter-squat position for 20 to 30 steps.
Clamshells are often done too fast. Slow down. A 1-second raise, 1-second squeeze at the top, and 2-second lower is better than rapid repetitions. Focus on feeling your hip abductors engage.
7. Wall angels (3×10)
Wall angels develop shoulder mobility and thoracic extension while activating the muscles that counteract rounded-shoulder posture. Pack straps pull your shoulders forward and inward; wall angels fight that.
Stand with your back against a wall, feet about 6 inches from the wall. Raise your arms to 90 degrees with elbows bent (like a goal post), and touch your arms and head to the wall. Slowly slide your arms overhead while maintaining contact with the wall. If you lose contact, stop at that point. Do 3 sets of 10.
Work toward full overhead range while keeping your arms, back, and head in contact with the wall the entire time. Most people lose contact around shoulder height - that's your current mobility ceiling, and that's exactly where you need to work.
Switch to prone Y raises: lie face down and raise your arms in a Y shape above shoulder level, squeezing your shoulder blades hard at the top. This removes the wall as a guide and forces your thoracic muscles to do all the work against gravity.
Wall angels teach your shoulders and thoracic spine to move together and develop strength in the muscles that keep you upright under load.
8. Ankle circles (2×15 each direction, each foot)
Ankle circles develop ankle mobility and proprioception (your sense of where your foot is in space). Your ankles are under load during every step, and mobility issues lead to poor foot mechanics, which cascade into knee and hip problems.
Stand on one leg (hold a wall for balance if needed). Lift the other foot off the ground slightly. Slowly draw circles with your foot - large, controlled circles. Do 15 circles one direction, then 15 circles the other direction. Repeat on the other leg.
Do the same movement on one leg without holding the wall. This increases balance demand and makes the ankle stabilizers work harder.
Stand on a folded pillow, foam pad, or balance board while drawing your circles. The unstable surface forces your ankle stabilizers, calf muscles, and foot intrinsics to actively fire to keep you upright while you work through the full range of motion.
The goal isn't speed; it's full range of motion. Large, controlled circles that take your ankle through its full range.
Strong ankles and proper arch support work together. This prehab routine builds ankle strength; supportive footwear maintains that strength under load. We recommend shoes with structured arch support for every ruck.
How to use this routine
You have three options for implementation depending on your schedule and preferences.
Option A: Pre-ruck warm-up. Do all 8 exercises with lighter sets (2 sets instead of 3, slightly fewer reps) before you put on the pack. This takes 10 to 12 minutes and warms you up perfectly for loaded walking. This is ideal if you're rucking several times per week.
Option B: Standalone prehab session. Do the full routine 2 to 3 times per week on non-ruck days. This takes 15 minutes and requires no equipment. Perfect if you ruck only once or twice per week.
Option C: Split routine. Do exercises 1 through 4 (lower body focus) before rucks, and do exercises 5 through 8 (core and upper body focus) on separate days. This spreads the work across your week.
Whichever option you choose, consistency matters more than perfection. Doing this routine twice per week prevents most injuries. Doing it zero times per week almost guarantees that you'll get injured if you ruck regularly.
Progressions by level

|---|---|---|---|
| Calf raises | 2 legs, flat ground (3×15) | Edge of step, full ROM (3×12) | Single-leg on step (3×8) |
| Bodyweight squats | Half or parallel depth (3×12) | Full depth (3×12) | Goblet squat or pause squat (3×10) |
| Glute bridges | 2 legs, quick tempo (3×12) | 2 legs, 2-sec pause (3×12) | Single-leg (3×10) or weighted (3×12) |
| Bird dogs | 1-sec hold (3×8) | 2-sec hold (3×8) | Banded or slow tempo (3×8) |
| Dead bugs | Standard tempo (3×8) | Slow tempo, 2-sec lower (3×8) | Weighted or both limbs (3×8) |
| Clamshells | No band (3×12) | Banded (3×12) | Banded walks (20-30 steps) |

Start at whatever level feels sustainable. If you're choosing between an easier progression you'll do consistently and a harder one you'll skip, choose consistency every time.
Prehab is half the equation - the other half is the right gear. A pack that doesn't fit properly forces your body to compensate, which is exactly what prehab tries to prevent. And proper shoes are critical for the ankle and foot stability these exercises build.
If you only do one thing from this routine, do glute bridges. Weak glutes are the root cause of most knee pain, lower back strain, and hip tightness in ruckers. Three sets, three times a week, two minutes of your life.
Research consistently shows that targeted prehab work reduces the risk of overuse injuries, particularly when focusing on the posterior chain (glutes, hamstrings, calves) - exactly what this routine emphasizes. The evidence is strongest for athletes who maintain consistent, progressive training in these weak link areas.
