I recently got myself a personal training in the effort of improving my general health and physique. However the first session included some exercises that resulted in a lot of aches and pains throughout my calves, knees, thighs and hips, taking me out of gym activities for most of the first week (Squats and lunges are now the bane of my life). Thinking it as the usual post-workout recovery, I tried to wait it out, but after the 4th day with very little improvement and with continued weakness in my knees/thighs, I opted to grab this little beauty... And I am very glad I did!
