CrossFit is all about pushing boundaries and building strength, endurance, and mental toughness through functional, high-intensity workouts. Every WOD from box jumps to Olympic lifts demands both physical power and mental focus. Recently, weighted vests have gained popularity among CrossFit athletes as a way to take training to the next level.
Originally used in military conditioning, these vests are now a staple in CrossFit boxes worldwide. By adding extra resistance, weighted vests help athletes enhance performance, increase stamina, and better prepare for benchmark workouts like Murph. Incorporating a weighted vest into your routine can amplify results, challenge your body in new ways, and help you reach your fitness goals faster.
Why Weighted Vests Are Essential in CrossFit
CrossFit focuses on functional fitness that prepares athletes for real-world physical challenges. Weighted vests complement this approach by adding resistance to dynamic, full-body movements rather than isolating muscles or relying on machines.
Athletes turn to weighted vests for several key benefits:
- Boosted intensity: Bodyweight exercises like push-ups, pull-ups, and air squats become significantly more challenging.
- Enhanced cardiovascular conditioning: Running, rowing, or burpees with added weight improve both aerobic and anaerobic endurance.
- Functional overload: Even weight distribution across the torso simulates real-life resistance, enhancing practical strength.
- Mental resilience: Performing WODs under extra load builds grit, focus, and determination.
With consistent use, a weighted vest becomes more than equipment it’s a training partner that drives growth and performance.

The Murph Workout and Weighted Vests
No discussion of CrossFit weighted vests is complete without mentioning Murph. This iconic Hero WOD honors Navy Lieutenant Michael Murphy and is widely performed on Memorial Day across CrossFit communities.
Murph consists of:
- 1-mile run
- 100 pull-ups
- 200 push-ups
- 300 air squats
- 1-mile run
Traditionally, men wear a 20-pound weighted vest, while women use a 14-pound vest.
The weighted vest transforms Murph into a true test of endurance, strength, and mental toughness. Regular WODs with a vest prepare athletes by building stamina, enhancing conditioning, and developing the discipline required to tackle this grueling challenge. For many, completing Murph is both a physical accomplishment and a testament to perseverance and community spirit.
Benefits of Weighted Vests in Functional Training
Weighted vests aren’t just for Murph they enhance a wide range of functional training exercises. Key benefits include:
- Increased metabolic demand: Just 10–20 pounds can raise calorie burn, making WODs more intense and efficient.
- Improved strength endurance: Movements like wall balls, box step-ups, and lunges become more challenging, helping muscles sustain effort over time.
- Enhanced running performance: Adding weight boosts cardiovascular conditioning and strengthens lower-body muscles, making athletes feel lighter and faster once the vest is removed.
- Better bodyweight control: Exercises like pull-ups and dips become more effective, building strength that translates directly to bodyweight mastery.
- Postural engagement: Evenly distributed weight engages core and back muscles, improving stability and posture.
The Murph Workout and Weighted Vests
No discussion of CrossFit weighted vests is complete without Murph. This iconic Hero WOD honors Navy Lieutenant Michael Murphy and is commonly performed on Memorial Day in CrossFit boxes nationwide.
Murph includes:
- 1-mile run
- 100 pull-ups
- 200 push-ups
- 300 air squats
- 1-mile run
Men traditionally wear a 20-pound weighted vest, and women a 14-pound vest.
Adding a weighted vest turns Murph into a true test of endurance, strength, and mental toughness. Training regularly with a vest builds stamina, conditions the body, and strengthens the focus needed to complete this grueling challenge. For many athletes, finishing Murph represents both a physical achievement and a symbol of perseverance and community.
Choosing the Right Weighted Vest for CrossFit
Not all weighted vests are built for CrossFit. To maximize performance and safety, consider these factors:
- Fit and comfort: A snug, adjustable vest prevents bouncing during runs and high-intensity movements.
- Weight options: Removable plates or sandbags let you tailor resistance to each workout.
- Breathability: Ventilated designs reduce overheating during longer sessions.
- Durability: Reinforced, abrasion-resistant materials withstand intense CrossFit training.
- Range of motion: Ensure the vest allows full arm and shoulder mobility for pull-ups and overhead lifts.
Choosing the right vest enhances comfort, performance, and results while minimizing injury risk.
Safety Considerations for Weighted Vest Training
Weighted vests are powerful training tools, but improper use can cause injury. Follow these safety tips:
- Start light: Begin with 5–10 pounds and gradually increase load.
- Prioritize form: Maintain proper technique; never let added weight compromise movement.
- Limit frequency: Overuse can lead to overtraining balance sessions with recovery days.
- Listen to your body: Sharp pain, joint discomfort, or excessive fatigue signals it’s time to scale back.
- Consult a coach: Beginners benefit from guidance to safely integrate weighted vest training.
Proper use enhances performance while protecting your body and recovery.
Programming Weighted Vests Into Your Routine
Incorporate weighted vests strategically to maximize CrossFit performance:
- Strength and skill days: Add the vest to accessory exercises like pull-ups, dips, and core work.
- Conditioning days: Wear the vest during MetCon circuits, including running, burpees, and wall balls.
- Benchmark prep: Use the vest in modified Hero workouts to train for Murph.
- Active recovery: Go for walks or hikes with a light vest to build endurance with low impact.
Balancing weighted vest sessions with traditional lifting and cardio ensures comprehensive strength, conditioning, and functional fitness.
The Mental Edge of Weighted Vest Training
CrossFit challenges both mind and body, and weighted vests intensify the mental aspect. Carrying extra resistance forces athletes to push harder, pace wisely, and maintain focus throughout a WOD.
Regular vest use also builds confidence: workouts feel lighter and more manageable when the weight is removed. This mental advantage carries into competitions and benchmark tests, helping athletes stay resilient, finish strong, and overcome fatigue when it matters most.
