I am moving a bit slow today after doing a heavy leg workout yesterday in the sand. I filled this big bag with sand and dragged it walking backwards for 15 minutes, which is supposed to strengthen the quad muscles and help aid the knees. I had an MRI done on my knees which showed almost no cartilage left in them, so now I am doing these exercises to make my legs stronger so I can avoid getting knee replacements. I want to keep playing beach volleyball but I need to get my knees better first with these exercises. The local contractor told me about doing these exercises and how they helped him fix them after ruining them from installing radiant heated flooring for so many years. I think if I am diligent with doing these each week a few times that I will be able to play again without damaging my knees any further. I carry heat pumps and other HVAC equipment during the day at work and need my knees to be strong so that I can keep working for a few more years. I think if I stick to the plan for a few more months I will be feeling a lot better and can play more games without any pain. So today I am a bit sore and will hit the local business a bit later to buy some things for my HVAC system and maybe get some of that pain relieving gel for my joints today. Besides that, I think today is going to be a day of rest.
