HIIT Routine Beta

I'm working on an online interval timer to be used in HIIT routines.  At this point I'm kicking around several possiblities, below are a few very rough beta interval timers using audio and video.

Exercises should be performed in order. 

Wt. is weight or setting. BW is bodyweight.  RM is the maximum weight that can be lifted for the number of repetitions.  e.g. 10RM is the heaviest weight you can perform 10 reps of the exercise with perfect form.  Your last rep should be near failure. 

Reps can also be duration in seconds for exercises without reps. 

Rest is in seconds.
