The PeakFitPro Isometric Exercises machine is a revolutionary App and Machine combo that create results in strength gains that sound almost too good to be true. Phenomenal results are not only typical, they are expected! From Pro powerlifters to the average Joe, you can expect your static strength to increase 50% to 300% in just 12 weeks. When you combine the safety of the PeakFitPro with the efficiency provided and expected results, there is no other gym or lifting system in the world that can compare to what the PeakFitPro has to offer. Imagine spending as little as 5 minutes PER WEEK lifting on the PeakFitPro and having better strength gains that anything you have ever done before. Plus, the safety is far beyond any conventional style of lifting. Without having to load a bar with heavy plates and the fact that all lifts are done from your strongest and safest range of motion, your chances of injury diminish significantly. It’s so safe, we have patients that are in their 80’s use it with amazing results. Who can benefit from the PeakFitPro: 1. Weight Loss: Adding 5-10 pounds of muscle will allow you to burn up to 60 pounds of fat per year, even while you sleep. Since muscle is metabolically active you have a sure-fire way to lose fat while you sleep, with just 5 minutes of lifting per week. 2. Bodybuilders: The name of the game is creating a stimulus that forces the body to grow muscle. Whether you decide to focus on hitting your PEAK weight week after week as Pete Sisco would prescribe, or having 1 set or rep brought to complete failure as Dorian Yates and Mike Mentzer would prescribe, the PeakFitPro can do it all. 3. Powerlifting: Nothing can touch the 5000 pound capacity of the PeakFitPro. Your Peak, high end strength gains, will be far beyond what you could accomplish with free weights. 4. Athletes of Team Sports: If you want maximum strength gains and superior safety, you can have all that in a 5 minute per week workout. This allows you to spend the other hours of training on sport specific skills. 5. Endurance Athletes: With the PeakFitPro your strength gains will be unparalleled by any other strength training options for the endurance athlete. You’ll have the ability to measure your lifts over time with our App in a way that has never been available before. Why would you ever use lighter weights that wouldn't stimulate the body in an optimum way to grow in strength the way the PeakFitPro can? There is no reason you should ever waste hours in a gym with traditional lifting for inferior results and increased wear and tear on your body. The PeakFitPro will take endurance athletes to the next level. 6. Diabetics: Put on 5-10 pounds of muscle and that muscle will eat up fat and sugar from your body plain and simple. 7. Osteoporosis: It’s called Wolf's Law. You put stress on a bone, the bone has no other choice but to grow and strengthen. Since you can do this so safely with the PeakFitPro, this is likely the most optimal way to build quality bone available today. 8. Longevity and Anti-Aging: Every piece of literature available suggests that exercise is perhaps the single greatest thing you can do to improve your health, longevity and youthfulness. The PeakFitPro can help you do this safely and efficiently. ANYBODY can find 5 minutes a week to use the PeakFitPro. Once you see the results, you will actually wish you could do more! Raising the intensity factor in your workouts can be done in 3 ways: 1. By progressively increasing the amount of weight you are using. 2. By progressively decreasing the amount of time it requires to perform a certain amount of work 3. By carrying each set to a point of total failure. The PeakFitPro does this like no other machine or lifting style out there today!
