ISC2 had a link on their website for some motivating, not boring, well maybe a little, OWASP Top 10 training CBTs, provided by Security Compass. If you are doing security code reviews this helps a little, or at least can be a good refresher.
The CBTs I took on this site were not very user interactive, which is good. I do enjoy just listening and watching. Every hour you do, counts as a CPE Credit.
