I purchased corefirst and haven't used it and almost cancelled today.  1) I do not have a space in my home long/big enough.  I can secure it, but there is no space around it.  I could use some guidance, if available. 2) I am not a yoga/Pilates person.  I'm a runner/soccer player with wrecked knees looking for a new program.  I struggle with online interfaces and I'm new to it.  help!  thank you, thank you!
