The sessions for IDEA World are still at the IDEA site; however, it appears that not all presenters make them available through this forum and only hand them out in person.
To check, click on ‘Conferences’, then ‘IDEA World’. Under sessions, you can click on ‘Session Handouts’ and see whether it is there. If it is not, you may try contacting the presenter.
I happen to come across your question and the Leigh Crews video for TRX Training for Active Adults will be out in August. (According to the information below) This link will take you directly there so you can check it out.
I hope this helps as it appears that the handouts are no longer available.
