Prevention — volume is factor #1
Prevention — volume is factor #1
There's one rule that runs through all training injuries: about 80% are not 'the movement is dangerous' but a spike in training volume outpacing recovery. Get this one straight and the rest of prevention is detail.
The shared root causes (true for both running and lifting):
A weekly volume increase above 10% is the #1 injury factor — stronger than foot type, shoes, or movement choiceExcessively high absolute volume (runners over 65 km/week, or lifting piled beyond recovery)Prior injury: about 80% recur at the same siteMissing strength training or core stability, leading to compensation
So a general prevention program:
Volume rule: weekly increase under 10%, with a deload week every 4-8 weeks (see recovery-science)Progress rather than jump: 'I feel good today, let me add 20%' is an injury incubatorStrength fortification: 2 strength sessions/week for runners (compound lifts plus hip abduction/external rotation specifics) cuts running injury risk in half (Lauersen 2014); lifters should mind push-pull balance and weak-link symmetryTechnique and full ROM: train with full ROM — long-term partial ROM actually produces more injuries via compensation (see mobility-flexibility)Warm-up and rest: dynamic warm-up before training, and 1-2 true rest days per week
On managing an acute injury, the current consensus has evolved from RICE to PEACE & LOVE (Dubois 2020, BJSM): in the acute phase (1-3 days) do PEACE (Protect, Elevate, Avoid anti-inflammatory modalities, Compress, Educate — inflammation is a healing signal, don't rush to suppress it); in the subacute phase do LOVE (Optimal Load, Optimism, Vascularisation, Exercise). No longer complete immobilization — early controlled loading actually accelerates healing (Bleakley 2012).

Common running injuries
Common running injuries
The van Gent 2007 (BJSM) review (17 epidemiological studies, n=18,000) puts the annual injury rate for recreational runners in the 19-79% range, concentrated in four categories:
Patellofemoral pain (PFP, 'runner's knee', 25-30%): pain below or medial to the patella, worse on stairs; caused by weak vastus medialis obliquus (VMO) plus weak hip abductors producing knee valgus (knee caving in) and uneven patellofemoral pressure; the fix is hip abductor strength (clamshells, side plank, single-leg squat) plus temporarily cutting running volume by 50%IT band syndrome (ITBS, 10-15%): lateral knee pain, especially downhill or during acceleration; caused by repeated friction of the iliotibial band over the lateral knee, worsened by weak hip abductors plus internal hip rotation; the fix is hip abduction/external rotation strengthening — don't stretch the IT band, it's connective tissue and can't be 'stretched out'Plantar fasciitis (8-10%): pain under the heel or along the arch, worst on the first step in the morning; caused by tight calves and Achilles plus a sudden mileage increase; the fix is calf stretching plus progressive loadingMedial tibial stress syndrome (shin splints, 13-20%): pain along the inner shin, most common in beginners or those suddenly ramping volume; caused by a periosteal response to repetitive impact plus a volume spike; the fix is reducing volume to a pain-free level plus a progressive rebuild
The shared root cause behind all four is still volume: a weekly increase above 10% outweighs foot type, shoes, or form by any measure (van Gent 2007); about 80% of running injuries recur at the same site (Saragiotto 2014); and about 80% of runners don't lift, leaving hip abductors and external rotators universally weak. Based on the Lauersen 2014 (BJSM) meta, strength training cuts running injury risk in half. The key point: the impact of shoes, form, and stretching is far smaller than volume management and strength training.

Common lifting injuries
Common lifting injuries
Keogh 2017 plus Aasa 2017 epidemiology identifies four high-incidence sites:
Lumbar spine (low back or muscle strain, ~30%): triggering movements are deadlift, squat, lunges, rows; the real cause isn't 'the movement is dangerous' but a volume spike plus rigid form under heavy loads plus weak core stability; the fix is deloading and strengthening the core (plank, dead bug, bird dog) — don't force PRsRotator cuff (~20%): triggering movements are overhead press, bench, dips, especially in people with anterior shoulder dominance (push far exceeding pull); caused by strong chest and anterior delts with a weak posterior chain; the fix is bringing the push-pull volume ratio to 1:1 or even pull-favored 1:2, plus isolated rotator cuff work (face pull, Y-T-W)Knee (~15%): triggering movements are squat, lunge, leg extension; mostly form that's too rigid plus weak hip abductors (knee valgus) plus volume spikes; the fix is full-ROM training plus hip strengthening plus volume management (see the 'knees-over-toes' debunk in mobility-flexibility)Elbow or wrist (high-frequency repetitive use, ~10%): triggering movements are bench, curl, heavy grip work; mostly tendinitis, not acute trauma; the fix is deloading plus changing grip plus nerve-glide therapy
The prevention rules share the same source as running: a weekly volume increase under 10% (the #1 factor, same as running); a deload every 4-8 weeks; push-pull balance plus weak-link symmetry (push-pull ratio at 1:1 or even pull-favored to counteract anterior dominance); full ROM, no partial-rep shortcuts; and listening to the body rather than the ego — stop immediately on sharp pain, while dull soreness is usually DOMS and you can continue, and deload that day if the same lift drops more than 5% in strength.

Red flags — when you must see a doctor
Red flags — when you must see a doctor
Most post-training soreness, tightness, and minor aches resolve with reduced load and recovery. But one category of signal is not 'train through it' — it means stopping and seeing a doctor. Memorizing these matters more than any training technique.
First distinguish two kinds of pain: dull pain is usually DOMS or mild overuse, improves after warm-up, and can be continued at reduced load; sharp pain is tissue protesting and should stop the current movement immediately.
The following call for stopping training and seeing a doctor:
A joint that pinches, clicks with pain, or locks and won't straighten — don't 'try one more time', this may be meniscus, labrum, or cartilage damageNumbness, tingling, or a sudden loss of strength in a limb — a sign of nerve compression or injury, especially when it radiates into the arm or legSudden marked swelling at the injured site, rapidly spreading bruising, or visible deformity — possibly a fracture, tendon rupture, or severe tearPersistent pain at rest, pain that wakes you at night, or pain that doesn't change with position — unlike a mechanical injury and needs investigationNo improvement at all after 2-3 weeks of reduced load and rest, or repeated recurrence at the same site
A few genuine emergency red lines (seek care immediately, don't wait):
Sudden chest pain or tightness during or after training, radiating to the jaw or left arm, with shortness of breath or cold sweat — treat as a cardiac event and seek immediate careA sudden severe headache ('the worst of my life'), with vomiting or altered consciousness — seek immediate careSudden one-sided calf swelling, warmth, and tenderness, especially after prolonged sitting/standing or long travel — suspect deep vein thrombosis (DVT), seek immediate care, and do not massage or stretch itLoss of bladder or bowel control with saddle-area numbness and leg weakness — suspect cauda equina syndrome, an emergency
This isn't scaremongering — it's the body speaking at its loudest. Exercise is medicine, and medicine still requires reading the label.
