How to walk with two hiking sticks
When buying hiking poles, buy the ones that are easily adjustable such as those with the twisting lock.
The higher priced ones have more durable hand grips, but otherwise the lower prices ones' locking mechanisms are sturdy.
Cut two short lengths of cord and tie your retracted hiking poles together when you are not using them.
Before using these poles, you should do some upper body exercises. A low intensity chest and upper back exercise with light dumbbells or cables will do.
