A core workout for runners: start with Level 01
If you want a simple core workout for runners to do today, start with this Level 01 routine. Move with control and stop before your form fades.
- Plank: 2 sets of 30 seconds.
- Lateral plank: 2 sets of 30 seconds each side.
- Bridge: 2 sets of 10 lifts.
- Plank with leg lift: 2 sets of 10 lifts per leg.
- Plank with knee tuck: 2 sets of 10 tucks per leg.
- Single-leg bridge: 2 sets of 10 lifts per side.
- Lateral plank with leg lift: 2 sets of 5 lifts per leg.
Use this on an easy or moderate running day, once or twice per week to begin. The goal is trunk control and hip stability for climbing, descending, and running well when tired—not an ab burn.

Why it matters
Stay stable when the trail gets messy
A good core routine builds strength through your trunk so your posture holds together when you climb, descend, trip, brake, twist, or run tired.
For trail and ultra runners, core work is not just gym filler. It supports downhill control, uphill power, efficient posture, and the durability needed for longer training blocks.
- Better control on technical descents
- More stable posture late in long runs
- Support for climbing, hiking, and power hiking
- Lower injury risk from fatigue and poor form
How to use it
Do the routine with control, not speed
Pair it with easier running
Do core work on an easy or moderate run day. Avoid stacking it with your hardest workout or longest run when your form is already compromised.
Keep quality high
Cut repetitions when needed. Fewer clean reps are better than rushing through sloppy movement and reinforcing bad mechanics.
Build consistency
Once per week is the minimum. Two to three times per week can work well when the sessions are controlled and placed intelligently.
