Legs + Core

Leg strength & durability

Strength

At the gym uses machines & weights. At home swaps in no-equipment versions of every exercise.

Warm-up

  • Bike or brisk walk5 min

    Raise core temperature before lifting.

  • Dynamic mobility5 min

    Leg swings, hip openers, bodyweight squats, arm circles.

Optional shakeout jog

  • Easy jog2 mi (optional)

    Loosen the legs before lifting, or skip straight to the weights if you'd rather.

Strength — legs

  • Squat4 × 6–8

    Squat to a depth you can control, driving through mid-foot. The biggest driver of lower-body strength.

    💡 Lower reps build strength without the soreness that wrecks the next day's run.

  • Sumo squat3 × 10

    Wide stance, toes turned out — emphasises glutes and inner thighs.

  • Bulgarian split squat3 × 8 / leg

    Single-leg strength and balance — don't skip the weaker side.

  • Calf raise (machine)4 × 12

    Full range, pause at the top. The calves can't be too strong for a runner.

  • Hip abduction (machine)3 × 15

    More glute-med work for a stable, efficient stride.

Core circuit F

  • Ab wheel rollout3 × 8–10

    Roll out only as far as you can keep the low back flat, then pull back. Elite anti-extension strength (start from the knees).

  • Toe touches3 × 15

    Legs up, reach for the toes by crunching the upper abs. Simple, focused upper-ab work.

  • Standing oblique cable crunch3 × 15 / side

    Crunch sideways against the cable. Loadable obliques for a stable, efficient torso.

  • Glute bridge march3 × 10 / leg

    Hold a bridge and lift one foot at a time without dropping the hips. Core + glute stability that protects the low back.

Cool-down & stretch

  • Light walk3–5 min

    Flush the legs and let the heart rate settle.

  • Hip flexor + couch stretch45 s × each

    Open the front of the hip after squatting/hinging.

  • Hamstring + glute stretch45 s × each

    Figure-4 and a forward fold to release the posterior chain.

  • Calf + ankle mobility45 s × each

    Wall calf stretch plus 10 slow ankle circles each side.
