Do I have to press the lap button each time I want to move on to the next exercise (synced a workout to my watch).

It depends how your workout is setup. For example, most of my exercices are configured to end on "Lap Button Press."

Another option is based on Reps (which I don't use mainly because often the rep count is wrong unless there is clear wrist movement).

Also, do you have your sets setup so that it's followed by a rest? For example, this exercise consists of 4 rounds (sets) followed by a 1 1/2-minute rest. Repeats 4 times

Hi! Thanks v much for your reply. Yes all the exercises are set to Reps (not lap button), and there are Rests between each set. I was hoping that when it had counted the correct number of Reps, the watch would move onto the next exercise. 

If I understand correctly, you want to do...

• Kettlebell Sumo deadlift, followed by 30 seconds rest. Repeat 3 times.
• Romanian Deadlift, followed by 30 seconds rest. Repeat 3 times.
• Mountain Climber, followed by 30 seconds rest. Repeat 3 times.

If that is the case it should look something like this.

Or are you wanting zero rest time between each of the first 3 exercises?
