Our trainers often train 2-3 clients in one session who will be doing the same workout plan but may do different weights and rep ranges. It would be great to have the ability to switch into the active client quickly as they do there set ,record there stats then the other client does there reps and these are recorded. The fluency of swithing between clients is a big plus to have so that you create the perfect tool for a trainer on his/her ipad or android tablet
