Training with the WaterGrinder
The missing link
The home bike, the elliptical machine and the treadmill are very effective tools for maintaining the cardiovascular system, but their big drawback is that all three only move the lower body. It is true that in addition to improving circulation, the muscles are also shaped, but the latter does not extend to the upper body.
The NOHRD WaterGrinder helps you train your upper body as well, as it works your arms, abs, shoulders, chest and entire back. The joints of your upper body and spine receive the necessary daily stimulation to maintain their flexibility in the long term.
Development of strength and endurance
Your legs are designed to be challenged multiple times throughout the day, so you need to train a lot more to get results. Unlike your arms, which only work for a short time and can rest for a large part.
The WaterGrinder takes advantage of this factor so that you can build muscle as efficiently as possible with the load through your arms when you start training. A workout is very intense and relatively short, yet you will always experience the effectiveness of the WaterGrinder.
Muscle work is similar to teamwork, one of the essential elements of which is proper communication. With the WaterGrinder, you move your muscles through their own system, thereby developing the connection between the nervous system and muscles, but your connective tissues are also not left out.
