Knee Pain: What worked for me during Shaun T's Insanity

In December, 2011 and January, 2012, there was significant discussion in the Insanity facebook group about knee pain - overuse injuries -  associated with Insanity.  An anti-inflammatory diet & various anti-inflammatory supplements are helpful, but proper form may be the culprit.  During jumps and squats, strive to keep the knee aligned with the direction of the toes, which Shaun T himself often cautions.   If the knee is not tracking over the toes during the movement,  this results in twisting/shearing of the joint and unwanted torque affecting the ligaments which can soon result in injury. Have your toes slightly pointed out in order to track the knee properly.  This helped me personally have a breakthrough in the Max workouts of month two with no more pain on jumps.  Also, land softly on your toes first, and don't jump up from your heels.

 For those of you whose pain is slightly above kneecap, this is referred to as patellofemoral pain syndrome, or "runner's knee", which involves the quadriceps tendon and tends to go together with weak hips.  This applies to me.  Pain at the base or below the patella is patellar tendonitis - "jumper's knee" - which involves the patellar tendon and is often associated with calf weakness.  I found these sources to be helpful for strengthening exercises and basic info for anyone interested:
