Why strength matters for a first half

Most first-time half marathoners are increasing their mileage more than ever before. That's exactly when injuries tend to appear. Two short strength sessions a week help your muscles, tendons and joints keep up with the extra running.

Weeks 1 to 4: learn the basics

Twice a week, 2 to 3 sets of 10 to 12:

  • Goblet squat
  • Romanian deadlift with dumbbells
  • Reverse lunge
  • Calf raises
  • Glute bridge
  • Side plank

Focus on technique. You should finish feeling like you could have done more.

Weeks 5 to 9: build strength

Add weight and drop the reps to 6 to 8. Swap reverse lunges for split squats and add step-ups. Introduce simple hops (pogo hops, 3 x 20 seconds). This is when you'll notice hills and late miles feeling easier.

Weeks 10 to 12: taper

Keep the weights but cut to 1 to 2 sets. Drop strength work completely in the final 5 to 7 days before race day so your legs are fresh.

Frequently asked questions

Do I need a gym?

No. Dumbbells or a kettlebell at home are enough for the first few months. A gym gives you more room to progress.

What if I only have time for one session?

One session a week is still much better than none. Prioritise squats, a hinge, single-leg work and calf raises.
