Knee problems can strike at any age, but as we age and naturally begin to lose muscle mass, strength and balance, you might notice problems cropping up more regularly. Some people will never struggle with knee pain, and that's great, but for others, it's a lifelong battle to continue exercising in later life while managing symptoms.The goal is to build and maintain strength, stability and mobility through exercise, and for that reason, I turned to UK-based physio Matthew Piff at Nuffield Health for three exercises he swears by.Check them out below, along with some benefits and step-by-step instructions.3 lower-body exercises from a physiotherapist“If I had to pick just three exercises that I would rarely skip for long-term knee health, they would be sit-to-stands, step-ups and single-leg calf raises," says Piff. "Together, they help build strength and resilience throughout the lower body, which can reduce stress on the knee joint and support day-to-day movement.” 1. Sit-to-stands

It strengthens the quadriceps, glutes and hip muscles, all of which help absorb load and reduce stress on the knee joint," explains Piff."It is commonly used in rehabilitation and osteoarthritis management because it improves both strength and independence in daily activities.The real benefit of sit-to-stands is that they help keep everyday movements feeling easier, helping you move more confidently. Whether it's getting up from the sofa, standing from a dining chair, or climbing the stairs, stronger leg muscles can help you move with greater ease and independence. They are also an excellent way of maintaining lower-body strength and function as we age."Get instant access to breaking news, the hottest reviews, great deals and helpful tips.Piff recommends 2-3 sets of 8-15 repetitions. "As this starts to feel easier, you can lower the chair height or add some weight to continue building strength," he adds.Sit on a chair with your feet flat and in front of your knees.Lean your chest slightly forward and push through your heels to lift yourself up without using your hands.When you’re in the standing position, sit your hips back and lower into the seat with control.2.
