We just added a new workout comments feature to the site. This allows you to provide feedback on any workout available on the site. If you really enjoyed a workout, why not leave a comment for the workout author? Also, if you modified a workout to make it more interesting, let the Dynoswim community know about it. Prior to submitting a comment you must first login to your account. If you don't have an account, create one now. This only takes a minute and it's free! In the coming weeks additional features will be implemented, stay tuned!
