Trail running strength

Strength for Trail Runners (Gym or No Gym)

You can get almost all the trail-running performance benefits without a commercial gym. This guide pairs with TrailSplits training plans: 2 short sessions per week, focused on climbing economy, downhill durability, and staying injury-free for the long run.

Quick start

Home / No gym

Bodyweight + hills + bench/stairs + backpack/dumbbells optional.

Gym / Weights

Barbell or machines with clear progression and controlled loading.

New to strength? Choose the option that you will actually do consistently.

Principles

Keep it easy: stop 2–4 reps before failure. You’re supporting running, not bodybuilding.
Bias single-leg: trails are uneven; single-leg control matters.
Train calves + feet: this is where a lot of trail injuries live.
Protect recovery: avoid heavy eccentric work right before long runs.
Progress slowly: add load or reps gradually and keep form strict.

No gym: the trail-runner strength plan

This track is built for runners who prefer outdoor, functional work. It’s low-friction and highly specific to hills and uneven terrain.

Key idea: make it “heavy enough” with leverage and loading. If you can do 10 reps easily, add weight (backpack + water bottles) so the last 2 reps feel difficult.

Equipment (pick what you have)

Bench/stairs/curb + backpack. Dumbbells/bands optional.

Session A (climb + control)

Bulgarian split squat: 3×6–10 / side
Single-leg RDL (dumbbell/backpack): 3×6–10 / side
Step-ups (bench/stairs): 3×8–12 / side
Calf raises: 3×10–15
Side plank: 2×30–45s / side

Optional finisher: 6–10 × 10s uphill sprints (full recovery).

Session B (downhill durability)

Step-downs: 3×6–10 / side (3–4s slow lower)
Lunge or sit-to-stand: 3×6–10 / side
Soleus raises (bent-knee): 3×10–15
Carry: 4×30–60s (backpack or farmer carry)
Dead bug: 2×8–12 / side

Movement pattern	No-gym option	Why it helps on trails
Squat / push	Bulgarian split squat	Single-leg stability for uneven terrain.
Hinge / pull	Single-leg RDL	Uphill power + hamstring resilience.
Step / climb	Step-ups on bench/stairs	Mimics big steps, roots, and steep hiking.
Eccentric / down	Step-downs (slow lowers)	Quads + tendons ready for long descents.
Power	10s hill sprints	Neural power with minimal joint impact.

Gym: the strength-purist track

If you like the gym or want very controlled loading, this track uses classic lifts and/or machines. Keep it runner-friendly: avoid grinding reps and prioritize movement quality.

Session A

Heavy: aim for ~RPE 8/10 (2 reps in reserve). Avoid grinding.

Squat or leg press: 3×5–8
RDL: 3×6–10
Calf raises: 3×10–15
Row/pull: 3×8–12
Side plank: 2×30–45s

Session B

Step-ups or split squats: 3×6–10 / side
Hamstring curl or hinge: 3×8–12
Eccentric quad focus (slow lowers): 2–3×6–10
Soleus raises: 3×10–15
Carry: 4×30–60s

How to progress

Weeks 1–2: 2 sets per movement, light loads, learn the patterns.
Weeks 3–8: build to 3 sets, add load slowly, keep reps smooth.
Peak weeks: reduce to 1–2 sets or cut to 15–20 minutes.
Taper: 1 short session early in the week; nothing heavy.

Safety notes

If you’re new to strength training or returning from injury, consider working with a qualified coach or PT. Pain that changes your gait is a stop signal.
