The data entry for reps completed doesn't make sense as it shows reps x kgs for all the excercises. I suggest better user interface in the app.

The number of reps for a particular excercise is not clear, each leg/side the mentioned number of reps, or half reps on each leg/side.

Rest between each rep. What I noticed was for easier excercises it was 90 seconds and for some difficult workouts it was 30 seconds.

If a instruction video is more than 2 mins... The work out time gets stretched out which inturn turns a 60 minutes workout to 90 mins.
