150 second plank (longest ever)
2 sets of 50 = pushups
Been doing a lot of swimming, and I have improved significantly in endurance. Nice
Anyone else want to post some results? I would love to see what others are doing.
Only 2 x 20 + 1 x 10 full body dips. Usually, I do at least 1 x 30. I think the pushups use the same muscles.
