Perking up the "200 Squats" app
Do not despair, my children!
Gather 'round, and I shall bring sunshine into your iPod/iPhone/iPad universe! 
Once you have mastered the 200 Squats app (awfully easy for a cyclist), you can let it reset. Reset, and add some PAIN! (doesn't that sound delicious?)
Grab your handy dumbbells and add military presses to your squats! Shift those weights from shoulders to straight overhead as you rise out of your squat. (a single weight in each hand will require a lot more scap and rotator cuff oomph to stabilize than a barbell, so switch to a barbell/bar until you are stronger if you have shoulder pain with this)
Not only have you just increased the work for your legs by adding weight to your torso, you've also just thrown your arms into a burning chaos of triceps melting terror!
Ahhhh, yesssss... feel it, my preciousssss...
