For those who don't know, I have recently developed moderate arthritis in my knees. I decided to share my workouts with those who have an intermediate to advance level in fitness but don't want to give up working out at an intense level. The book does start out with a beginner workout routine but that same routine could also be bumped up to a more advance level by using heavy weights or thicker workout bands or tubes.
Here is one example of my beginner routines and this workout is on the floor:
Bad Knees Boot Camp Floor Workout #1
Clams with a weight or elastic band or without
V-situps (The 3rd variation & I like the weight in my hands not between the legs)
Break and RepeatPerform each exercise for 30 seconds to 1 minute depending upon your fitness level. There is a 15 second break between each exercise. Go through all of the exercises and repeat 2 - 3 times. Cool-down
