There are several ways to build strength in the water and drag sets are one of them.
To perform a drag set, wear a T-shirt or an apron with pockets in your main swim set. Try to swim at your regular pace and power through the water as your t-shirt or apron “holds” you back. Your warm up and cool down should not include the drag suit.
These drag sets are great to do during your endurance base training phase – during the off-season and in the early part of in-season training.
Give it a try in your next swim workout!
