Lesson 2 of 4 in Stamina & The Mental Game
Strength & Mobility
Strength keeps your standing position stable and protects your joints; mobility lets the bike move under you without fighting you. For most riders, two or three short sessions a week of big, multi-joint movements — hinges, squats, lunges, pulls, pushes, carries and anti-rotation core work — plus grip endurance and ten minutes of hip, ankle and upper-back mobility is enough. Move well first, then add load. Together they help you hold your position longer, so your body doesn't give up before the trail does.

Why strength and mobility matter in hard enduro
Hard enduro is ridden standing, in a half-crouch, for hours. Your legs and hips hold that position. Your trunk transfers every hit from the pegs to the bars. Your grip holds on, and has to stay relaxed while it does. When any of those gives up, your arms take over, your grip tightens and your riding falls apart.
Riding itself tires the grip fast. After a 15-minute motocross ride, one study measured "a reduction of 16%" in maximal handgrip force. A study of amateur motocross riders found "a significant reduction of 11.5% and 9.2% for the right and left hands" after a training session. The authors of another motocross study concluded that riders should "train not only aerobic and anaerobic capacity but also to use strength and power training".
Mobility matters because the bike moves under you. Stiff hips and ankles push you into a sitting position, and a stiff upper back rounds your shoulders and loads your forearms. The body positioning lesson shows the stance these muscles are holding.
What to focus on
The movements that matter most for riders, with simple versions you can do at home or in a basic gym.
| Area | Exercises | What it does on the bike |
|---|---|---|
| Hip hinge (posterior chain) | Romanian deadlift, kettlebell deadlift, hip thrust, back extension | Holds the forward-bent standing position; protects the lower back when you lift a stuck bike. |
| Squat and lunge | Goblet squat, split squat, step-up, lunge | Legs that absorb hits and hold the crouch without burning out. |
| Pull | Rows, pull-ups or assisted pull-ups | Balances the pushing and gripping posture; supports the shoulders. |
| Push | Press-ups, overhead press | Pushing the bike, getting up after a fall, stable shoulders. |
| Carries | Farmer's carry, suitcase carry (one side) | Grip endurance and a trunk that resists being pulled sideways. |
| Anti-rotation core | Side plank, Pallof press, dead bug | A stable middle that transfers force between pegs and bars. |
| Neck and upper back | Band pull-aparts, face pulls, shrugs | Holding your head up under a helmet for hours, with your shoulders back. |
| Grip endurance | Dead hangs, towel hangs, light wrist curls and extensions | A grip that lasts without a death grip. |

How much, and how often
The major guidelines agree on the basics.
- Frequency. The American College of Sports Medicine recommends two to three days a week for beginners, rising to three or four days for intermediate lifters. The World Health Organization's baseline for all adults is muscle-strengthening work for "all major muscle groups on 2 or more days a week".
- Effort. The NHS's plain-English version: do strengthening exercises "to the point where you need a short rest before repeating the activity".
- Order. Big before small. The ACSM advises "large before small muscle group exercises, multiple-joint exercises before single-joint exercises". Deadlifts and squats first, grip and core last.
- Progression. The ACSM suggests a "2-10% increase in load" once you can do one or two reps more than your target. Small steps, not big jumps.
- Grip and muscular endurance. For endurance rather than maximum strength, the ACSM recommends "light to moderate loads (40-60% of 1 RM) be performed for high repetitions (>15) using short rest periods (<90 s)". That's the right model for forearms that need to last hours, not lift a car once.
Two or three sessions of 30 to 45 minutes a week beat one long one. Choose movements you can do well at home or in a simple gym.
A 40-minute strength session
Twice a week, with at least a day between. Start light enough that every rep looks the same. When all sets feel easy at the top of the rep range, add a little load.
| Time | Drill | What to focus on |
|---|---|---|
| 0–5 min | Warm-up: easy row or cycle, then bodyweight squats, hip hinges and arm circles | Warm, not tired. |
| 5–13 min | Romanian deadlift or kettlebell deadlift, 3 × 8–10 | Flat back, hips back, bar close to the legs. |
| 13–21 min | Goblet squat or split squat, 3 × 8–10 (each leg) | Knees track over toes, full control. |
| 21–28 min | Row and press-up, alternating, 3 × 8–12 each | Shoulders down and back. |
| 28–33 min | Farmer's carry, 3 × 30–40 m | Tall posture, firm but not crushing grip. |
| 33–36 min | Side plank and dead bug, 2 rounds | Ribs down, slow breathing. |
| 36–40 min | Light wrist curls and reverse curls, 2 × 15–20; one relaxed dead hang | Light load, high reps: endurance, not size. |

Grip, forearms and arm pump
Arm pump is the forearm tightness and loss of grip that comes on during hard riding. Grip endurance helps, but it's only part of the answer. A relaxed grip, levers set for standing, suspension that isn't harsh, and legs that hold your weight all matter as much. The arm pump guide covers riding, setup and training habits, and when arm pump needs a doctor.
For the gym, train grip for endurance, not size: hangs, carries and light, high-rep forearm work, plus some wrist extension work to balance all the squeezing.
Recurring, severe arm pump can be a medical condition. A study of racers with forearm chronic exertional compartment syndrome notes "riders typically report that braking becomes progressively more difficult". A 2025 review of the condition found "motorcycling and motocross were the most frequent sports (66%)" in the research, but also that "its diagnosis is challenging because of the lack of clearly established diagnostic criteria." The NHS advice on compartment syndrome is clear. See a GP if "you keep getting pain, numbness, swelling or have difficulty moving a part of your body when you exercise". Call 999 or go to A&E if you have "sudden, severe pain". The NHS notes that the sudden form can start "after an injury", so severe, swelling pain in a forearm or lower leg after a crash is an emergency, not arm pump. Don't train through either.
Mobility where riders get tight
Riders get stiff in three places: hips (from sitting and from gripping the bike), ankles (from stiff boots) and the upper back (from leaning over the bars). The ACSM recommends flexibility exercises for each major muscle group, about 60 seconds per exercise, at least two days a week. The routine below takes about ten minutes, after a ride or a strength session.
Move slowly into each stretch and breathe. Mobility should feel like work, not pain.
A 10-minute mobility routine
| Area | Exercise | Dose |
|---|---|---|
| Hips | Deep squat hold | 60 s |
| Hips | Hip flexor lunge stretch | 60 s each side |
| Ankles | Knee-to-wall ankle rocks | 60 s each side |
| Upper back | Open-book rotations, lying on your side | 60 s each side |
| Hamstrings | Lying hamstring stretch | 60 s each side |
| Forearms | Wrist flexor and extensor stretches | 30 s each way, both arms |

Fitting it around riding
- Keep strength sessions away from big ride days. Heavy legs the day before a hard ride make you ride worse and practise bad habits.
- Lift early in the week, ride at the weekend. A common pattern that leaves time to recover.
- Before a big event, cut volume in the last week but keep a short session to stay sharp.
- In season, two short sessions a week maintain what you built. Don't stop altogether.
- Warm up before you ride, too: five minutes of leg swings, squats and arm circles before the first technical section.
Strength and mobility mistakes
Training arms and grip to exhaustion every session.
Fix: Big lifts first, grip last, and train it for endurance with lighter loads and higher reps. Size isn't the goal.
Adding weight before the movement is right.
Fix: Move well first, then load. Add weight only when your back stays flat through every rep.
Skipping legs because riding is 'arms'.
Fix: Legs and hips carry the rider. Strong legs are what let your arms relax.
Stretching only when something hurts.
Fix: Ten minutes, twice a week or more, keeps you mobile. Waiting for pain is too late.
Heavy leg day before a ride.
Fix: Plan sessions so you arrive at the bike fresh.
Progress cues
It's working when:
- You feel more stable standing on the pegs, and your legs last longer in technical sections.
- You can hinge at the hips with a flat back, without rounding.
- You can hold a relaxed dead hang for 30 seconds or more.
- You can hold a deep squat with your heels down.
- You finish rides with fewer nagging aches in your back, neck and forearms.
Strength and mobility questions
Do I need a gym?
No. A kettlebell or two, a pull-up bar and your bodyweight cover everything on this page. A gym makes progression easier once you get stronger.
Will strength training make me slower or bulkier?
Not at two or three sessions a week alongside riding and aerobic work. The aim is a body that holds position for hours, not maximum size.
Does grip training prevent arm pump?
It helps with forearm endurance, but relaxed technique and bike setup matter as much. See the arm pump guide.
Should I lift in race season?
Yes, but less. Two short sessions a week keep your strength without leaving you tired for the weekend.
