Forget about the expensive gym membership; invest $25 and get unlimited access to an unbelievable workout right in your own home.  Today, I'm going to show you how to build and install your own pullup bar for only about $25.  Alternatively, we're also going to install some gymnastic rings.  The rings could be a better option if you have limited space or if you want something that can go with you when you travel.  Pull-ups are one of the very best ways to build upper body strength, tone your muscles, improve posture, and crash-proof your human chassis.  You're going to look better, feel better, have more self-confidence, and avoid injuries.
