This pullup bar requires no modification to work with standard residential door frames. You can use it near the door frame you walk under the most, and stowe it out of sight when you're entertaining. Take it with you on the road, as it works with hotel door frames as well.

I was a pushup purist until I tried out these neat little handles. They make pushups more difficult to perform, but reduce strain on the shoulders (a welcome feature for those of you who enjoy high-volume training). I was frankly suprised at how many more normal pushups I could perform after using the perfect pushup for just a few weeks.

It has especially noteable effects on the lower abdominals and lower back, two areas which are difficult to train with both weights and pure calisthenics.

Buy new: $15.99
These are affordable, reasonably comfortable ankle weights for use with walking and calisthenics. Don't sprint with these (or any ankle weight) as it will scratch up the back of your ankle, even through socks. I found out the hard way. You'd be suprised how much more difficult even walking a couple miles can be when you throw these ankle weights into the mix.

Grip training is fun and yields tremendous dividends in the form of increased performance in any activity where holding on to things is important. Captains of Crush are excellent for training and measuring hand strength. If you make it to the #2 gripper or higher, you will enjoy a competitive advantage in all things grippy.
