If you're the last person on earth who hasn't heard or seen the Perfect Pushup, it's time you got clued in. Launched in 2006, the Perfect Pushup is the pivoting round handlebars your friend, brother and/or roommate has been using to maximize their upper body potential for the last three years.

It's time to jump on the bandwagon and use the Perfect Pushup to engage more elements of your body into one exercise. Using the 360-degree rotating bars, the Perfect Pushup enables you to activate your arms, shoulders, chest, back and abs for a better push-up that also minimizes injury and strain.

The good news is Perfect Fitness, the people who developed the Perfect Pushup, have turned their sights to other workout tools, which employ similar methodology to correct form while maximizing function.

The Perfect Pullup is a bar that can be attached to any door frame and allow you to perform a variety of pull-up, dip, or even pushup-movement against a stable but mobile bar. By clipping-on a set of rotating handlebars, a person can incorporate a swiveling hand-grip to change the difficulty of the exercise and slowly improve their pull-up ability.

If you live in a shoebox-size apartment, or are looking for affordable tools to add to a home gym, the Perfect Pullup and Pushup are fantastic machines that require little space or money. One pair of Perfect Pushup bars can cost as little as $30 and the Perfect Pullup bar with accessories costs $90.

The devices are simple to use and provide almost instant results. After a short workout with Alden Mills, co-founder of Perfect Fitness, I felt as though I could easily go home and effectively use the products on my own. My arms got a better workout in 30 minutes with his Perfect tools than any workout I've had using machines at the gym or doing general free-weight exercises.

Soon-to-be-released will be the Perfect Situp and the Perfect Cardio. Again, these tools are aimed at being highly effective machines to augment basic exercises, but I was mixed on their ability to develop core muscles or provide a cardio workout gym-enthusiasts would enjoy.

Personally, I exercise my core and legs harder than my upper body, so the pull-up and push-up machines worked my weaker habits better. I have a very developed core, so I found the Perfect Situp to be less impressive when it came to working my abdominals. The Perfect Situp aligns your body from head-to-toe and forces you to slowly curl each and every abdominal muscle. If you are a person who tends to do "lazy sit-ups" this machine will prevent you from slacking off and might be the perfect addition to amp-up your ab-workout.

Perfect Cardio is a hand-held machine made up of two swiveling handlebars molded together in one unit, the size of a computer keyboard, and weighs 8 lbs. You can hold on to the Perfect Cardio machine and rotate through multiple planes of movement without readjusting your grip. The device forces your body to rely on core strength to adapt to the change in weight as you move the Perfect Cardio around your body. This machine definitely requires some time and practice. Having a DVD to guide you through a workout would be best, but this machine is definitely geared more towards women.

While the Perfect Cardio got my heart rate up, I'm not sure I could last through an entire 30 or 45-minute class using this machine. My muscles would max out fairly quickly, and I'm pretty sure you can't attach it to your legs for any lower body exercise.

Both of these products are still in development, so perhaps a few of their drawbacks will be addressed before production, but for now I'd stick with the Perfect Pushup and Pullup.

Now if they could only come up with a Perfect Leg Press...
