Mountain Climbers improvement suggestion

The most frustrating thing about the mountain climbers exercise if the lack of feedback from the trainer. I cannot see how many reps I have left and often give up early only to find out I only had 10 reps left. Have the trainer call out at the halfway, 20 left, 10 left, and 5 left points.|||..even better, just drop it from the list of different exercises. Oh how I squirm when the next exercise in line is announced as "Mountain Climbers!!".
