Prehab (Prehabilitation)

Rucksack Palsy

Numbness, tingling, or weakness in the arms or hands caused by a backpack's shoulder straps compressing the brachial plexus nerves. Almost always solved by loosening the straps, raising the pack on the back, or adding a sternum strap.

Plantar Fasciitis

Inflammation of the plantar fascia — the band of tissue along the arch of the foot. Common in ruckers from too-rapid increases in load or distance, especially on hard surfaces. Usually responds to load reduction, calf strengthening, and proper footwear with arch support.

Shin Splints

Pain along the inner shin (medial tibial stress syndrome) from overuse of the tibialis anterior. Common when ruckers ramp volume too quickly or transition from soft surface to pavement. Treatment: deload by 30%, strengthen tibialis anterior, address footwear cushioning.

DOMS (Delayed Onset Muscle Soreness)

The 24-72 hour soreness that follows new or unusually intense exercise. Normal after the first few rucks; DIMINISHING soreness over weeks signals adaptation; PERSISTENT or escalating soreness signals overreach.
