If you have a cracking sound in your knees and a certain "uneasiness" or even pain when doing movements like going up the stairs, do not disregard this. Eventually, it could grow into a bigger problem as it was in my case.

Knee problems have always been an issue for me. I suppose, it lies in my family's genes since my mother and his father had the same problem as me. It started as I was about 14 years old It didn't hurt at all and I didn't feel anything disturbing. Just this strange cracking sound. So I though "whatever… I can live with it!". Unfortunately, it changed during the following years.

The cracking sound got louder and I felt a small pain in my knees. I mean, I still could live with this problem, but I was worried if it could get worse at the age of 30, 40 or 50? So I went for an specialist's advise and was told that there was nothing wrong with my knees and that the sound would go away with the age. I was also advised that I should start running and train my quads as it usually helps in this kind of problem.

However, running didn't change much. I think, it even got a bit worse since I was running on concrete back in Madrid and this impact is not very healthy for the knee joints. (Follow my advice and go run on a beach if you have one nearby! You will avoid the trouble in the long run! ;-))

Fortunately enough a friend of mine suggested to try cycling. It doesn't have much impact on your knees, trains your whole legs and is fun as hell! So I started with simple spinning classes half a year ago. Very soon I was doing 2 classes in a row, 3 to 4 times a week. Apart of dramatically improving my endurance and cutting all that fat I have saved up during my time off running, I have noticed an incredible improvement in my knee joints! There's no pain anymore and the sound is almost nonexisten. Hooooray!!

Two months ago I have bought a mountain bike (which was my biggest fitness investment ever) and have started to train going up and down the hills in my area. Sometimes aroung 100 miles in one go! This is really fun and gets very addicting! Leg strength, endurance and overall health keeps improving. I am even considering to participate in a few mountain bike marathons this fall!!

Summing up, cycling is probably the best choice if you have knee problems (better than running or leg training at the gym). Good road or mountain bikes can get somehow expensive, but they are worth every penny! I consider my bike as my best investment since the benefits you get are worth much much more. Cut the costs on other crap. Get rid of junkfood and stop bying stuff you do not need. Save money for things that are really matter!
