I have been going to the gym for a year and really used to enjoy the challenge of my workout and the 'high' afterwards. Now, due to longstanding disabilities, I have progressed as far as I can. My workout is VERY routine and boring, now.

I am limited in the types of movements that I can do. I cannot do a lot of movement of my upper arms, due to stenosis, bone spurs and spondylitis in my neck.

My knees each have different issues, one is weak and unstable, due to un-healed ligaments, the other has chondromalacia patella and cannot bend more than 30 degrees.

Both ankles have PTTD. I wear two smo's all of my waking hours for the ankle problems and knee braces for each knee, while doing the treadmill.

The recumbant bike causes SEVERE coccyx pain, due to ankylosing spondylitis.

The elliptical, causes the PTTD to flair up. I had to wear a walking 'boot' for three months, due to a recent flair up of PTTD.

Despite all this, I am VERY high energy and active. At the gym, I do the same thing EVERY day!! 40 minutes on the treadmill, which I go as fast as I am capable (3 mph) and the incline as high as I can (8-10%) The weight machines, I have increased the weight as much as I can, don't have time for more reps.

Any ideas on how I can make it more challenging??

wow I am impressed with your Motivation. You mentioned weight machines....do you do free weights?
