For todays workout you’re going to want to be comfortable in the water. This combination of aerobic and anaerobic movements is ideal for building a strong cardiovascular system, as well as maintaining muscle mass with the water resistance.
(Max of 5 min break in-between rounds, if you cannot complete a full length underwater do not worry it will come with time, just take a minute and continue from where you came up.)
9 lengths, 1 underwater
8 lengths, 1 underwater
7 lengths, 1 underwater
Etc… all the way down to one of each.
I recommend starting off with the underwater length to make it easier.
