We have designed two models with two resistance levels. Randma 1.0 is the level for beginners with a resistance of 20 lbs. Randma 2.0 is the advanced level with a resistance of 40 lbs for those who have already trained with level 1.0.

For best results we strongly suggest that you upgrade to Randma 2.0 advanced level after 1 week of using level 1.0.


Why we have made two different resistances?


Your facial muscles are not used to this kind of training for the advancer one.


So we HIGHLY SUGGEST that you start with our Level 1 Randma 1.0 to reduce the risk of injury. Warm up your muscles and also achieve the best results possible.
