WHAT IS RECIPROCATING / ALTERNATING FUNCTION?
This button enables you to work opposing muscle groups at the same time; ie biceps and triceps. When normal mode is selected, all channels will contract and relax at the same time. However, when the alternating/reciprocating function is selected, even channels will be on and odd channels will be off during one cycle and will switch back and forth with subsequent cycles. The main advantages of using this function is to reduce workout time and hence decrease result time.
