The overlooked key to fitness? Strengthening your joints and tendons

Isometric exercises, like planks or lunge holds, require holding a position for an extended period. In these positions, your muscles are firing, but you’re also working on the alignment of the joint and working the tendon to hold that position, says Wulke. Ho adds that while ligaments and joints cannot technically be trained directly like tendons, you can support their health by strengthening the surrounding muscles and encouraging proper movement patterns.

Wulke often programs training days with a mix of goals for her athletes: “high” days for muscle and strength development and “low” days focusing on alignment, isometric holds, and mobility. But most people don’t have enough time to dedicate separate days for joint-specific work. Instead, try integrating these movements into your existing strength training sessions. Consider adding a few sets of isometric holds during your warm-up or as a finisher.

(Is cracking your joints bad for you?)

During your workouts, focus on the eccentric phase of your movements. Slow down and maintain control throughout the exercise to help you ensure proper form. You can also use higher reps and lower weight to reduce the risk of overstressing connective tissues.

Last, Hinson recommends incorporating low-impact exercises such as walking, cycling, Pilates, water aquatics, and yoga. “Taking care of and improving the structures that make the joints stronger and more flexible—it really will pay huge dividends in keeping [people] out of my office and away from injury,” he says.
