Just a quick bug report: At https://musclewiki.com/Exercises/Male/Traps_middle/ when you want to go next page it directs you https://musclewiki.com/Exercises/Male/Traps%20(mid-back)/2 which causes 404. It should direct to https://musclewiki.com/Exercises/Male/Traps_middle/2 . I assume root cause of this is that you are getting next page link from title.
