1. Kick WITHOUT a kickboard, On your side. This improves balance in the water and with practice, will improve your kick. Also, stretch your ankles- ankle inflexibility is the #1 reason for a weak kick!
2. One-Armed Freestyle. Freestyle only using one arm to stroke, while keeping the other arm at your side. Rotate your hips as if you were swimming full strokes. Breathe to the opposite side of your stroking arm.
WARNING: This is a more advanced drill and will take some practice to get it right!
3. 3/4 Catchup Drill. Many coaches will have you doing Catchup Drill- touching your hands out in front in freestyle with each stroke. The problem with this is that it keeps you on your stomach too long, when you want to be rotating from one side to the other. 3/4 Catchup means as you slice one hand into the water, start your pull with the other hand. It’s “almost” catchup. This helps with balance and rotation.
