One action of talking less is basically 4-5 groups of 8- 12 each. Don't chat with one piece of equipment, and talk less. If you and I take turns, there is no rest time. If you have a foundation, it only takes them one minute to finish the work. It happens that they usually exercise by themselves, and it is ok to take a break of about one minute between each group. . . Of course, it works best when two people are together.
