I wondered if there was any benefit to adding kick drills to an age grouper’s repertoire, particularly using The Brick kickboard by Fike?
The Brick is a weighted kickboard that encourages better positioning in the water – like a pool buoy I suppose – but the marketing bumpf also says that The Brick provides a total body workout and helps strengthen the core, so from that point of view would it be a beneficial tool to improve my overall strength for swim, bike and run?
The only time I would typically include kicking drills would be as a form of recovery after a big run day.
Very light kicking to loosen the legs only (e.g. 6 x 25 light kick at the start of a workout)
To improve strength I would recommend using pool buoy and paddles in the pool. And lots of it. Specific strength work.
