Day-One Standards That Keep This From Getting Messy#

This is a first-week practice, so the win is organization: swimmers know where to start, how to circle swim, how to leave on time, and how to stop without crashing into each other. We’ll teach two strokes (free/back) with just a few cues, then layer in turns and a short interval set so they understand what “on the send-off” means.

Lane order: Put swimmers in lanes by comfort level after the first easy warm-up. If you’re unsure, start mixed and then move 1–2 swimmers after you watch two lengths.
Circle swim rule: Always swim on the right side of the lane. If you pass, do it at the wall only (tap feet once, pass on the next push).
Wall rule: If you’re resting, stay tight to the corner—don’t block the middle of the wall.
Start rule: No diving today. All starts are from the wall or in-water push-offs.

What We’re Teaching (And What We’re Not Yet)#

Freestyle focus is body line, relaxed exhale, and a steady kick that doesn’t bicycle. Backstroke focus is body position (hips up), straight kick, and consistent rotation without “sitting.” Turns are introduced as skills, not speed: we want safe, repeatable wall habits (tight tuck, feet placement, strong push and streamline).

We are not chasing yardage. The aerobic set is short by design—just enough to teach send-offs, pacing, and finishing at the wall.

How To Coach This Group In The Water#

Keep them moving in short repeats. When you correct, pick one thing, then immediately give them a rep to apply it. Use the pace clock for structure, but don’t let the clock run the practice—if a lane is confused, pause that lane at the wall, demo once, and restart them together.

0:00–0:06

Deck Talk And Safety Setup

▾

Meet on deck with everyone standing behind their lane (not sitting on the blocks). Quick roll call, then point out depth markings and where you want bags/shoes.

Non-negotiables today: no diving, no underwater breath-holding contests, and when I whistle you stop and grab the lane line.
Lane etiquette preview: swim on the right, rest in the corners, and leave space—no one leaves until the swimmer in front is past the flags.

Watch for: who is listening and who is already wandering—pair those kids with a responsible lane mate before you get in.

0:06–0:16

In-Water Warm-Up And Lane Sorting

▾

Start in the shallow end. Everyone does 4 x 25 easy (choice of free or back) with plenty of rest; your job is to observe and quietly sort lanes by comfort/speed.

On each 25, require a wall touch and a push-off in a tight streamline (hands stacked, head tucked).
Cues: “Long body.” “Blow bubbles.” “Touch the wall every time.”

Common issue: swimmers stop mid-pool to stand. Fix: give them permission to go to the lane line and hold it for 5 seconds, then continue—no standing unless it’s a safety issue.

Adjustment: if a lane is too crowded, convert to 2 x 25 and 2 x 12.5 (to the flags) so everyone keeps moving without pile-ups.

0:16–0:28

Freestyle Body Line And Breathing

▾

All lanes, same focus. Swim 6 x 25 freestyle at easy effort with 20–30 seconds rest; you’ll give one correction per swimmer max each length.

Watch for: one goggle in/one goggle out on the breath and hips staying near the surface.
Cues: “Exhale underwater.” “Turn your head, don’t lift it.” “Kick behind you, not under you.”
Common issue: holding breath then gasping. Fix: at the wall, make them demonstrate a steady exhale for 3 seconds before the next push-off.

Adjustment: if breathing is a mess, switch the middle 2 reps to side-kick (one arm extended, one at side) for 12.5 out/12.5 swim back to reconnect body position.

0:28–0:31

Water Break And Clock Lesson

▾

Quick drink and a 60-second pace clock demo. Stand them where they can see the clock.

Show the big hand and explain: “If I say ‘leave on the :00 and :30,’ that’s when you push.”
Coach move: pick one lane and practice a fake send-off on deck: point, count down, and have them step forward in order.

Watch for: swimmers who don’t know their order—assign numbers on the spot (1–4) before you restart.

0:31–0:43

Backstroke Body Position And Kick Timing

▾

Setup: everyone starts on their back in the water, one hand on the wall. Do 4 x 15m back kick (to halfway) then easy backstroke to the wall; repeat twice.

Cues: “Belly up.” “Small fast kick.” “Eyes up—don’t curl.”
Watch for: steady splash at the surface and hips not dropping when they breathe (backstroke breathing is continuous).

Common issue: knees popping up and big bicycle kick. Fix: tell them “kick from the hip,” then physically demonstrate a tiny kick on deck; next rep they must keep toes just under the surface.

Adjustment: if they can’t stay straight, have them swim next to the lane line and lightly brush it with their hand on each stroke.

0:43–0:53

Kick Set With Boards And Streamline

▾

Setup: boards out for freestyle kick; then boards away for streamline kick on back. Run it as 8 x 25 alternating: odd = free kick w/ board, even = back kick in streamline (hands locked overhead).

Cues: “Tight core.” “Fast feet.” “No big knees.”
Watch for: kick tempo stays the same when they get tired—no sudden huge kicks.

Common issue: board shoved underwater and head lifted. Fix: tell them “board rides flat—chin down,” and if needed have them hold the board by the bottom corners to keep it level.

Adjustment: if shoulders fatigue in streamline, allow hands at sides for one rep, then return to streamline on the next.

0:53–1:05

Turn School: Flip And Open Turns

▾

Setup: split each lane in half—two swimmers at a time at the wall, others wait at the flags. You’re teaching wall habits, not racing.

Step 1: 3 fast strokes into the wall, then stop and touch (learn the distance).
Step 2: tuck and somersault away from the wall mid-lane once, then come back and do it closer.
Step 3: at the wall, choose flip turn or open turn, but everyone must finish with feet on wall, tight streamline, and a strong push.

Cues: “Last stroke to the wall.” “Tuck tight—knees to chest.” “Feet flat, then rocket push.”
Common issue: stopping short and grabbing the wall. Fix: put a visual target (lane line color change/marker) and require their last stroke to pass that target before they turn.

Adjustment: if a swimmer gets disoriented on flips, keep them on open turns today but require the same tight tuck and streamline push-off so the habit transfers later.

1:05–1:08

Water Break And Lane Etiquette Reset

▾

Drink, then 90 seconds of lane rules with everyone at the wall in their actual lane order.

Circle swim: right side down/right side back.
Passing: only at the wall after a toe tap.
Resting: corners only—middle is for turning.

Coach move: have each lane point to where they will rest (right corner/left corner). If they can’t answer, you haven’t set the lane yet.

1:08–1:25

Intro To Interval Training: Short Aerobic Set

▾

Setup: write the set on a whiteboard where they can see it: 10 x 25 freestyle @ :45 (or adjust per lane). Goal is steady effort and leaving on time, not sprinting.

How it runs: swimmers leave in order with 10–15 seconds spacing. After rep 5, give them 30 seconds extra rest, then finish reps 6–10. You walk the deck and coach one point per swimmer.

Watch for: consistent breathing pattern and a clean finish to the wall every rep.
Cues: “Same speed every 25.” “Bubbles first, then breathe.” “Finish to the wall.”
Common issue: they blast the first two and fall apart. Fix: tell them their job is to make rep 10 look like rep 2; if not, they slow down and hit the same stroke count range.

Adjustment: for swimmers who can’t hold 25, they do 10 x 12.5 to the flags on the same send-off, touch the wall, then rejoin the line at the back.

1:25–1:30

Cool-Down And Two-Point Recap

▾

Easy 100 total (choice: 4 x 25 easy) with long streamlines off every wall. Keep it quiet so they can feel the water.

Recap question 1: “Where do you rest on the wall so you don’t block turns?” (Make them point.)
Recap question 2: “What happens underwater before you breathe in freestyle?” (Answer: exhale.)

End with: next practice we’ll repeat the interval idea and add one new skill—don’t change everything at once.

What You'll Need#

Kickboards (1 per swimmer if possible)
Pull buoys (6–10 to share)
Swim fins (optional, 6–10 pairs for teaching body line)
Pace clock (wall clock) or stopwatch
Small whiteboard and marker for writing send-offs
Lane lines in place and backstroke flags set

How To Run The Interval Set Without Losing The Lanes#

The interval set is the most important management piece today. Before you start it, physically walk the lanes and assign an order (1–2–3–4) at the wall. Tell them: “You leave when the top hand hits the number. If you miss it, you go on the next one—no panic sprint.”

Spacing standard: Start with 10–15 seconds between swimmers. If anyone is getting caught mid-pool, increase spacing immediately.
Finish rule: Every repeat finishes to the wall. No stopping short. If they stop short, they owe a clean finish on the next one before they rest.
Coach position: Stand at the 15m–25m area for two repeats to watch body line and breathing, then move to the wall to watch turns and push-offs.

What you’re looking for is consistency: same stroke count range, same breathing rhythm, and a push-off that actually travels. If a swimmer is gassed, don’t punish them with more distance—keep the distance, give them more rest, and demand cleaner technique on the next rep.

Common Breakdowns You’ll See (And Exactly What To Do)#

Freestyle head-up swimming: They lift their head to breathe and the hips drop. Why it happens: they’re holding their breath. Fix: stop them at the wall and have them do 3 “bubble-bubble-breathe” cycles holding the gutter, then swim 25 free breathing every 3 strokes with one goggle in/one goggle out.
Scissor kick on freestyle: Legs split on the breath. Why it happens: they’re using legs to balance. Fix: put a pull buoy lightly between thighs for one 25 to feel straight line (or tell them to “zipper-kick: toes brush each other”). Remove it and repeat immediately.
Backstroke sitting: Knees come out of the water and they stall. Why it happens: kick is too big and hips drop. Fix: 15m back kick with hands at sides, eyes up, and cue “small fast splash—hips up.” If they still sit, have them press their chest up and squeeze glutes on the push-off.
Turn chaos at the wall: Everyone stops in the middle and talks. Why it happens: they don’t know where to rest. Fix: assign corners: odd numbers rest right corner, even numbers rest left corner. If they block the middle, restart the rep—no lecture, just redo it correctly.

Adjustments For Real-World Constraints#

If you have only one coach: Keep the group together more often. During technique work, run “down-and-back together” so you can correct at one wall. Save individual feedback for the kick sets where they’re stationary on boards.
If lanes are crowded: Convert some 25s to 20 seconds of skill + 10 seconds rest at the wall (kick in streamline, 6-kick switch, or wall-turn reps) so you reduce mid-pool collisions.
If a swimmer can’t yet swim 25 nonstop: They still stay in the lane. Give them 12.5m targets (to the flags) with a legal wall touch, then walk back along the gutter and rejoin. Same send-off, shorter distance.
If you don’t have enough kickboards: Partner-share: one kicks down while the other does streamline kick on back without a board, then swap on the return. Keep the lane moving.

What To Hit Next Practice#

Next practice, keep the same lane rules and send-offs, then add one new layer: freestyle catch timing (front-end extension into an early vertical forearm feel) and backstroke arm recovery with relaxed shoulders. Expect the first breakdown to be breathing rhythm under fatigue—so bring back short 25s on an interval and insist on “exhale the whole way” before you increase any distance.

Frequently Asked Questions#

How do you place swimmers into lanes on the first week without embarrassing anyone?▾

Start everyone mixed for the first easy warm-up. Watch who can swim 25 without stopping and who needs breaks. Quietly move 1–2 swimmers at a time: “You two slide to Lane 2 with me.” Frame it as matching space and speed, not ability.

What if several swimmers can’t do a flip turn at all?▾

Don’t force it. Teach the wall approach and streamline push-off first, then do somersaults mid-pool (no wall) so they learn the tuck. At the wall, let them do an open turn today as long as they touch, tuck, plant feet, and push off in a tight streamline.

How many repeats should I expect in the first interval set?▾

For brand-new swimmers, 8–12 x 25 is plenty if they’re actually leaving on time and finishing at the wall. If the lane falls apart, cut the number of repeats and keep the send-off structure—quality over volume.

How do you stop passing and collisions in crowded lanes?▾

Increase the gap (15–20 seconds), enforce rest-in-the-corner, and only allow passes at the wall. If someone touches feet mid-pool twice, stop that lane and reorder it by speed immediately.

What should I do with swimmers who get anxious about backstroke (can’t go straight)?▾

Give them a job: count strokes from wall to flags and keep one arm at their side while they kick on their back. You can also have them backstroke next to the lane line and “brush the line with pinky” to stay straight. Keep them in a slower lane until they can hold direction.
