If your shoes don't fit properly or are inappropriate for the surface where you're exercising, they can put undue stress on your joints and tendons. Make sure you're wearing the right shoes for your activity, and that they fit well and are in good repair.  If the tread of your shoes is worn, it may be time to get new ones. Most shoes are only "good" for a particular distance or amount of time. After that, any support and benefits you got when the shoes were newer will disappear. If it suits your budget, go to a specialty store and get specially fitted for shoes that will best support your feet while performing your chosen activity. To truly treat quadriceps tendonitis, you need a diagnosis and treatment plan from a qualified doctor or physiotherapist. Quadriceps tendonitis is not a condition that typically just gets better on its own.  The doctor will ask you questions to get a complete understanding of your knee problems, including a history of your knee pain, any prior injuries, and when you first started experiencing issues. Most times, quadriceps tendonitis is diagnosed based on your history and a physical exam. If necessary, the doctor may have X-rays or MRIs done on your knee to further assess your condition before making a final diagnosis. Recurrence of quadriceps tendonitis occurs more frequently when athletes don't allow enough time for recovery and rehabilitation before resuming their previous level of activity. Your tendon needs at least a month of physical therapy to fully heal.  A physical therapist will prescribe exercises designed specifically for your injury, your normal activity level, and the activities to which you want to return. If you're a more serious athlete who regularly works with a trainer or coach, your physical therapist may work with them to develop your rehabilitation plan. Lay on your back. Keep one leg straight, and bend the other so that your foot is flat on the floor. Activate your core and lift your torso until your body forms a straight line from your knee down to your shoulders. Hold the position for 10 seconds and think about which muscles you feel working the most.  The muscles you should feel working the hardest are your glutes. If you feel the exercise more in your back, hamstrings, or quads, this means one of two things: either you are compensating for a muscle imbalance, or you're not doing the exercise with correct form. Check and correct your form as necessary, and do the exercise a few more times to see if you get the same result. If you still feel the exercise somewhere other than in your glutes, try some exercises to strengthen your glutes. Muscle imbalances can cause an uneven gait that redistributes your body weight, placing more strain on the joints of one side of your body. If you're working with a physical therapist, they will assess your gait and see if you need assistance in this area.  Retraining your gait is not a short-term project. Particularly if you've gotten used to walking a certain way over the course of several years, it can take a long time to fix problems. In addition to gait retraining, you'll also have to strengthen opposing muscles to correct the imbalance.

Article: Every few months, it’s a good idea to put on a pair of gloves and gently run your hands through the grass. It should feel kind of like you’re finger-combing your hair. This helps pull out any dead foliage and keep your evergreens looking their greenest. Work gloves are ideal for this process, but if you don’t have a pair of those you can always use rubber gloves. Combing through the grass usually removes most of the dead foliage. If some brown blades remain after combing, though, you can always trim them out with gardening shears. Just remember to trim at the base of the blade to remove as much of the dead foliage as possible. Like deciduous grasses, evergreens generally need an annual trim. Unlike deciduous grasses, though, you don’t need to prune that much off evergreens. Use your gardening shears or hedge trimmers to cut any brown or spent flowering tips off the grass. Cut your grass back to new growth, which should still be green. The exact length that you need to cut depends on what type of grass you have and how much your grass has grown out. That’s why you typically go by color instead of length for evergreen grasses.
