From Miles to Muscles

RPE 3

Setup: Mats in rows with a clear metre beside each for swinging legs. Open with the sales pitch this crowd needs to hear, because runners attend strength class the way cats attend baths: running is thousands of single-leg hops in a row, so tonight is not a day off running — it is the class that buys next year's miles. Ask who is racing soon and who is nursing anything; niggled calves and grumpy knees get named now, not discovered mid-lunge.

How it works: Runner-specific from the first minute: leg swings front-and-back then side-to-side with a hand on the wall, ankle circles, twenty slow calf pumps, walking knee hugs down the mat, and open-the-gate hip circles back. Finish with two rounds of five slow air squats and five hip hinges — the two shapes the whole night is built from.

What to say

“Swing the leg, not the torso — the pillar stays quiet while the pendulum works.”
“These calves have a job tonight — wake them gently now, thank me later.”
“Tell me about the niggle before the class finds it for you.”

Easier

Halve all swings; squats to a bench.

Harder

Add ten walking lunges at the end, unweighted and unhurried.

Single-Leg School

RPE 6

Setup: Three stations set in bays: split squats beside a wall for balance fingers, step-ups on the bench, and single-leg deadlifts with a dumbbell option. Thirds of the room per station, four minutes a bay including the demo. This is the block that earns the class its keep — running injuries live in the gap between two strong legs and one wobbly one.

How it works: At each bay, quality sets rather than a clock: split squats 8 per side with the back knee kissing towards the floor; step-ups 8 per side, whole foot on the bench, standing to a full tall finish with no push off the trailing leg; single-leg deadlifts 6 per side, hips square, back leg reaching long — held dumbbell optional and unweighted encouraged for week one. Rotate on your call. Coach the wobble warmly: a shaky single-leg deadlift is the exercise working, and the wall is always in bounds.

Common mistakes

Single-leg deadlift hips opening to the sky — cue 'headlights on the floor' and shorten the range.
Step-up push-off from the floor leg — slow the tempo until the top leg confesses.

Rounds: 3 bays × 4 min, 2–3 quality sets per bay

What to say

“Down the lift, not forward — the front knee tracks over the laces, the torso stays proud.”
“Step-ups: make the top leg do the whole job — the bottom leg is a passenger, not a springboard.”
“Hips level like you're balancing a cup of tea on your tailbone.”
“Wobbling is the paying customer here — smooth means it's too easy.”

Easier

Split squats holding the wall; step-ups on a lower step; deadlifts as toe-tap hinges with both toes staying down.

Harder

Dumbbells at every bay; split squats slow to a 3-second lower; step-ups add a knee drive at the top.

Calves, Feet & Springs

3 rounds × [12 + 12 raises + 20s spring]RPE 6–7

Setup: Steps and wall space shared out; shoes stay on but tell them this block is why running shops sell so many calf sleeves. The calf takes more load per stride than any muscle a runner owns, and almost nobody trains it on purpose.

How it works: The calf matrix, three rounds: 12 straight-knee calf raises off the step edge with a slow three-second lower, 12 bent-knee raises for the deeper soleus — the true mileage muscle, then 20 seconds of quick low hops on the spot for anyone whose calves and Achilles are happy, or fast heel raises flat on the floor for anyone whose aren't. Between rounds, 30 seconds of foot work: toes spread wide, big-toe presses with the other toes lifted. Sell the soleus line hard — bent-knee raises feel wrong and work best.

What to say

“Slow down off the step — three seconds, heel below the edge, that lowering is the medicine.”
“Bent knee changes the muscle — it should feel deeper and duller, that's the mileage engine.”
“Hops are small and springy, heels kissing the floor — you're a bouncing ball, not a rocket.”
“Any Achilles that speaks up mid-set gets the flat-floor version — no debates with tendons.”

Easier

All raises flat on the floor with two feet; skip hops entirely.

Harder

Single-leg raises off the step; hops go 30 seconds with a forward-back pattern.
