Virtuagym is all about connecting you to your fellow healthy-lifestyle lovers from all over the world.
Additionally to this, you are able to post messages on the profile of others.
Whether you want to congratulate them on their new unlocked achievement or help them stay motivated, it's always nice to leave a message for someone.
As a user, you can decide who gets to see and post to your profile, so it might happen that you are unable to post on someone's profile. If you want to connect with them, you can try and send them a buddy request.
