My knees have been really creaky lately and I realize I have to do more strength training to help them. I found a workout from the nytimes that is specifically for this and I did it for the first time today. Most of the exercises were pretty hard for me - a sign that I needed them! So, I'm going to try to integrate these into my exercise program a couple times a week, at least to start. I can potentially go to once a week if I get better at it.
It took me 20 minutes to go through all of them, and then I added some planks - a minute on forearms and a minute of high plank, and then dead bug when I dropped opposite arm and leg between them. After I did some bench presses, and a couple other arm exercises. Probably should look for a nice arm workout like this to complement the routine.
I know I should be doing 30 minutes of strength training 2x a week faithfully, I'm really going to try harder to do it. Once I get going it's not really that painful.
