The unit I bought is a H2O Fitness PhysioTrainer UBE. The S.O. No. 11546. The P.O. No. DS-0773148. The other discription for this unit is [9506.91.10.11] Upper Body Ergometer for Excercise. The question I have is does this unit have tension when using in the reverse cycle? The unit I used at the physio had tension in both directions and the reverse tension helped much more than the reverse. I thought that this unit would also have the same functions. Please let me know if this unit has tension in the reverse direction. read full review »
