I am a former personal trainer, I am always looking for new modalities. I'm 65 and had some injuries, this has been a great addition to my home gym! I actually just ordered a new Rumblex 4D so now I have 2 great pieces of equipment!
Bought for lymphatic flow. Have used 3 times. Has improved swelling in ankles. Has improved back/hip tension when seated for car rides. I am not as stiff when I get out of car! Am highly satisfied. There is an extended list of contraindications you should check before purchasing.
