What the Weighted Vest Murph Is and Why It Matters
The Murph is one of the most popular hero WODs: 1 mile run, 100 pull-ups, 200 push-ups, 300 air squats, and a final 1 mile run — traditionally done wearing a 20 lb vest for men and 14 lb for women. Done correctly, it builds endurance, mental toughness, and work capacity. Done incorrectly, it can wreck your shoulders, knees, and pride. This guide focuses on practical, outdoor-first advice for finishing Murph with a weighted vest without blowing up your training plan.
Choosing the Right Weighted Vest for Murph
Fit and mobility are the priorities for Murph. You need a vest that stays snug during runs and burpees, but doesn’t limit shoulder or hip mechanics when you’re doing high-rep push-ups and squats. For most athletes I coach, two vests stand out as dependable options.
Many athletes favor the WOLF TACTICAL Simple Weighted Vest for its low profile and decent mobility during burpees and push-ups. If you need a more training-focused option with plate capacity, the 5.11 TacTec is also worth considering for stability under heavy running and dynamic movement.
Fit checklist
- Snug around the chest—no bouncing during the run.
- Shoulder straps should allow full scapular movement for pull-ups and push-ups.
- Easy to don and doff between rounds if you plan to scale.
How to Scale Murph Without Losing the Point
Scaling isn’t cheating; it’s smart training. If you’re new to weighted vests or Murph, consider these options:
- Do a half-Murph (500–300–150 reps) with prescribed run segments.
- Use a lighter vest (10–14 lb) or add rep partitions such as 10 rounds of 10 pull-ups, 20 push-ups, 30 squats.
- Buddy up: alternate movement and rest; keep intensity manageable.
Warm-up, Pacing, and Recovery Tips
Never start Murph cold. A 10–15 minute warm-up focusing on hip hinge, shoulder activation, and short accelerations will save reps later. Pacing matters: the runs should be controlled, and partition pull-ups so you don’t fail mid-WOD. After Murph, prioritize mobility, rehydration, and protein. If you’re doing multiple weighted sessions per week, limit other heavy upper-body days to avoid overuse.
Estimate Calorie Burn: Quick Calculator
If you want a rough idea of calories burned during Murph with a vest, use the rucking calorie tool below. It’s built for weighted walking and load-carrying, and gives a useful ballpark for planning nutrition around heavy workouts.

Practical Notes from an ISSA-Certified Trainer
I recommend starting light and building weeks of volume before trying a full-weighted Murph. Preston Shamblen, who lost 90 lbs through rucking, weighted-vest training, and disciplined nutrition, still lists weighted vests as one of the most reliable ways to maintain a lower bodyweight and burn fat consistently. Keep Murph as part of a broader plan—not a one-off test of ego.
Finish strong: use sensible pacing, pick a vest that fits your movement, and treat scaling as strategic training. Murph rewards preparation more than it punishes hesitation.
