Well I always found it amusing to see people walking with two poles. But I confess that in the last couple of years I have started using one pole.

It helps with balance in tricky places - three legs are better than two - and it takes some of the pressure off my left knee at times. I had arthroscopic surgery and had about 60% of the meniscus removed from the knee about four years ago.

So I would suggest - go with one pole. I think two are overkill, unless you've got two bad knees. To give a bit of perspective, I am 57 and played rugby for 20 years. I hit the gym almost every day.
