Pump up that heart
In order to raise your heart rate and improve cardiovascular fitness, water jogging for 1- to 3-minute intervals will do the trick. Studies have shown that water joggers actually burn more calories than land joggers, sans the impact on joints and tendons, of course.
Toys for fitness
Some core and balance exercises do require the use of water playthings like water log or “noodle” and a volleyball-sized inflatable ball. These exercises strengthen your core muscles which help your body maintain balance.
