I am noticing popping sounds from my knees when I bend my knees after my leg is static for sometime. I am currently on day 65. Is this knee popping sound something anyone has faced? It is pretty frequent thing and not a once in a day type thing. I did plyo just now but took most of the high impact off. Please let me know if this is normal or I need to change something.

Modify is the right approach. No need to injure yourself. Popping can be a result of many factors, from old injuries to overworked joints.

I suffered a pretty bad shoulder break when I wrecked a motorcycle years ago and it pops like crazy. My right knee has also started to have twinges. This is a lot of work in a short period of time and it's really important to emphasize form and quality over quantity.

You might also want to include a joint supplement if your not taking one. It takes a few weeks of taking them to start getting the benefits but they have been proven to work. I take a glucosamine/chondroitin/MSM combo. read up online and see what might be best for you.

Ya as my knees havent had any injuries I think the only reason could be overworking them. I do tend to go pretty low(close to parallel) on my horse stance and below parallel on my squats.I will go and get the joint supplements as well.

How are you knees now.

I am experiencing the same symptoms and I am on day 45. Symptoms only started about a week or so ago, just beginning to feel discomfort in the knee joints.

Actually after finishing round1(90 days) I gave it a complete break. For the past 2.5 months. Now I do not feel the discomfort and popping as frequently as before. It took about 1.5 months for it to heal.
The flipside is that now I am gaining back weight so I have begin round 2 with reduced leg/standing exercises.

I have a pain in my right knee that was very subtle to start, but this morning it was a little more pronounced. I went out and bought some glucosamine, chondroitin, and msm pills today with the hopes that it will help my knee out. I think I'll also get a knee brace before doing anymore leg workouts. I've heard great things about glucosamine, so I hope that will help.
