Benefits of using manga or comic strips

Content comprehension aided by pictures

Since it is comic strip format it is easy to understand and I think it is good to understand using pictures with less language used. (No. 9)

Sensory understanding

I could understand what to do in one glance. (No. 10)

Request for information

Information on calories burnt

It would be helpful to have the average value of calories burnt (No. 6)

Specify expectations regarding results using numbers

I think it is good to know the extent of the difference between when one does small things diligently and when one does not in the form of numbers. (No. 8)

Strengthening the antecedent factors of actions

Improvement in the intention of carrying out actions

On some occasions I made it a point not to sit in the train and I would like to continue this (No. 4).

Recognition and understanding of the importance of actions

I reconfirm things that I was thinking of doing by looking at the pictures and then practice them. (No. 9)

Awareness of the importance of changes in actions

I thought that I could also do such things and doing them would make a difference (No. 8)
