5. Change Your Seat
When you sit all day at work, this takes a very serious toll on your body. You will be shortening your hamstrings and tightening them, while at the same time lengthening and weakening your quadriceps. This combination can result in uneven pressure being placed on your knees, which in turn leads to pain and difficulty walking and running.
Using a seat that keeps your legs in a different position, or even just making sure to get up regularly, can make a big difference and solve this problem.
