What it takes: Lower back strain
Rounding your spine under load in deadlifts, squats or rows strains the muscles and discs of the lower back. Fatigue at the end of a set is when form most often breaks down.
Heavy loads through your back, shoulders and wrists, set after set.
Lifting builds muscle and bone and protects you as you age. Most injuries come from poor form, too much weight too soon, or skipping recovery. The lower back, shoulders and elbows take most of the strain.
Rounding your spine under load in deadlifts, squats or rows strains the muscles and discs of the lower back. Fatigue at the end of a set is when form most often breaks down.
Bench presses, overhead presses and dips load small rotator cuff muscles that are easy to overwhelm. Programs heavy on pushing and light on pulling leave the shoulder unbalanced.
Heavy gripping, curls and pull-ups load the tendons that attach at the elbow. Pain on the inside or outside of the elbow that builds over weeks is a common overuse sign.
Muscles grow between sessions, not during them. Training the same muscles hard every day, sleeping poorly and under-eating protein all slow recovery and raise injury risk.
A program built around heavy lifts and little mobility work can leave hips and upper back stiff, which makes it harder to reach good positions under the bar.
See a doctor for back pain that runs down a leg, numbness or weakness, or any sudden sharp pain with a pop during a lift. Shoulder pain that wakes you at night or limits raising your arm deserves an exam.
