The steps

How it works

  2. Make the second 100 faster than the first.
  3. Rest 45 seconds.
  4. Swim 4 of these.

Coaching point

Hold back early, bring it home.

Safety: Only swim with a lifeguard or coach watching and, under 14, a grown-up within arm’s reach.

Make it fun

Play it, don't drill it

Game version

Pool-deck follow-the-leader: one person leads a dryland movement and the group copies. Swap the leader each time.

Challenge

Pick a level: Less (slower or smaller), Core (as written), More (one extra twist). Aim for smooth form and compare only with your own last time.

Story

You are an explorer crossing the pool deck like a jungle.

My best

Beat your own count

Aim for smooth form and compare only with your own last time. Only your own number counts: today against last time.
