Do your knees ache after climbing stairs, or does your wrist go stiff after typing or gardening? It might be due to injured or otherwise unhealthy tendons. Also called sinews, tendons are cords of fibrous tissue that connect muscle to bone. They carry the load behind nearly everything you do, from lifting groceries to running errands.

Unfortunately, they also get less blood flow than muscle does, which is why they heal slowly and need real care.
To that end, here are six habits worth building before pain forces the issue.
Warm up before any activity
Cold tendons don’t bend the way warm ones do. Stiff tissue tears more easily under a sudden load, which is exactly what happens when you launch into a run or an hour of yard work without warming up first. Five to ten minutes is usually enough to raise blood flow and get tendons ready to work. Dynamic moves like leg swings or arm circles beat static stretching here, mainly because they rehearse the actual motion you’re about to do rather than just lengthening a muscle.
Weekend gardeners and runners coming back after a few weeks off sometimes skip this step, perhaps in their excitement to get started. However, that gap between “used to moving” and “moving again” is exactly when tendons are least prepared. It only costs a few minutes, but not warming up can cost you weeks of pain and inactivity.
Strengthen the muscles around your joints
A warm-up gets you through one session, but overall strength protects tendons over months and years, because stronger muscles take on more of the load. Where you focus that strength should follow what your days actually look like. Anyone glued to a keyboard for hours daily needs stronger wrists and forearms, parents lifting kids in and out of car seats need stronger hips and core, and people who stand most of their work shift need stronger calves and ankles. Push too hard too fast, though, and you’ll outpace what your tendons can adapt to. The good news is you don’t need a gym for any of this. A couple of dumbbells or a resistance band will do the job just as well.
Feed your body the right nutrients
Tendons are mostly made of collagen, and the body produces less of it as you get older. The muscle you’re building through strength work still needs raw material to keep the tendons underneath it from becoming the weak link. Protein and vitamin C both play roles in that repair process, so citrus, leafy greens, and lean protein earn their place on the plate here. After forty, when collagen production starts tapering off on its own, a daily collagen supplement can pick up some of the slack your diet leaves behind. You can buy collagen online nowadays without a prescription, but it’s still best to consult your doctor and look for reputable retailers.
Give repetitive movement a break
Strength and nutrition only go so far if you never let a joint rest. Overuse is still one of the most common reasons tendons act up, whether the culprit is running, typing all day, or repeating the same motion on a job site. The fix isn’t complicated: alternate hard days with easy ones, and give any heavily used joint at least one full day off each week. It takes almost no extra time, and the payoff shows up in tendons that hold up longer.
Stay hydrated throughout the day
Recovery also depends on something people rarely think about: water. Tendons hold a fair amount of it, and when you’re dehydrated, they stiffen and become more prone to small tears. Steady sipping throughout the day keeps that fluid balance where it needs to be so tendons glide smoothly against the tissue around them. Sugary drinks don’t help much here, and neither does coffee since caffeine acts as a mild diuretic. A simple enough fix is keeping a water bottle within arm’s reach and staying hydrated, especially if you’re at a desk or on your feet most of the day.
Listen to pain instead of pushing through it
Even with everything above in place, some discomfort still deserves attention. Pain is the tendon’s way of flagging a problem, and persistent aching, swelling, or stiffness after an activity isn’t something to mask with a painkiller and ignore. Rest, ice, or seeing a doctor sooner beats pushing through to finish a workout or wrap up a task. Left alone, a minor strain can turn into something that takes months to heal.
Tendon health comes down to whether you keep showing up for these habits long after the novelty wears off, not whether you get any single tip exactly right. That’s what turns ordinary maintenance into real protection down the line. The point was never to erase every ache for good; it’s to build a body that bounces back quickly when pain or fatigue does show up.
