The off-season should be your favorite time of year to get into the pool and work on your stroke. If you have technical elements that need attention, the early off-season is the perfect time to work on them. Check your ego at the door and swim slowly. That’s right, drop a lane or two at your masters workout and give yourself permission to swim slowly on your own. Following are drills that will make you more efficient come springtime if you’re willing to make the investment now. If you want to make significant improvement, get in the water as often as you can. Aim for 4-6 swims each week if you want to make major changes. Even a 20 minute session will be helpful.
