We're again looking at starting swimming again after your rest period, every athlete needs a period of rest after the season. The drills in this period are important. You're trying to practice really good stroke mechanics and then you need to take that really good form into your main swimming sets. So. with the single armed swims make sure you rotate to both sides, when your arm is extended out front and when it passes under your hips going to your thigh. With Catch Up to kick Board please come off the side of the board not the back, keep your elbow high and point your forearm and hand to the bottom of the pool as one unit.
The main set is a series of race paced swims . 6 of each 25m, 50m and 100m done at the same pace. Starting with the 25m swims should allow you to maintain good stroke mechanics throughout. However, keep checking the time to make sure you're maintaining a good race paced effort.
