www.hikerino.de With a daily short hike and these simple exercises I was able to get my knee back into shape after a bad injury. It took me about 6 months to recover it and was able to successfully thru-hike the Appalachian Trail without any problems. For the best results I suggest to train every other day. 3 sets with 10-15 reps each. If you should feel any pain, stop training and take a rest day. No need to push it to the limit.
