To really work your abs in the shallow end,
simply hold on to the edge, bring the outer knee up and then kick it out to the side,
in and down. This is a variation on the kickboxing side kick. So simply up, out, in and down.
It’s a lot easier in the water. For the side kick, you can either hold onto the wall or
a noodle. This is a variation on another kickboxing move. Begin by bringing your right knee up
to about hip level, kicking it out to the side, in and down. Up, out, in and down. Again,
go at a pace that’s comfortable for you, and also be sure not to stretch your range of
motion. If this is as far as you can go, that’s fine. Work your way up. Once you’ve done 10-12
on the right side, switch it up, and same thing on the left side. This is a great workout
for your obliques, your waist muscles.
