What’s the Purpose of a Weighted Vest and How Do You Use It?

Weighted vests are designed to add external resistance to your natural movement, helping you build strength, increase endurance, and make everyday workouts more effective. They’ve gained popularity for being low-maintenance but high-impact especially without the need of any bulky gear , just strap it on and move.

Why It Works

Research supports the use of weighted vests for enhancing performance. A 2015 study published in the Journal of Science and Medicine in Sport found that warming up with a weighted vest improved leg stiffness and running economy, which can directly translate to better running performance and muscular efficiency during training.

Additionally, previous findings in the Journal of Strength and Conditioning Research have suggested that external loading through weighted vests can improve neuromuscular activation and metabolic response, particularly during functional and high-intensity workouts.

How It’s Used Across Fitness Styles

• Strength & Bodyweight Training: Make exercises like push-ups, squats, and pull-ups more demanding and more effective.

• Cardio & HIIT: Boost calorie burn and heart rate by wearing a vest during runs, stairs, or circuits.

• Cross-Training & Functional Fitness: Popular in CrossFit-style WODs (like the iconic “Murph”) for building endurance and grit.

• Rehab & Light Conditioning: Lower-weight vests are often used for posture improvement, balance, or resistance walking.

• Sports & Agility Drills: Athletes wear vests to simulate match-day stress and improve power under pressure.

Hands-Free Advantage

One of the best things about a weighted vest is that it keeps your hands free and your movement natural. There’s no need to hold dumbbells or worry about grip fatigue because the weight is evenly distributed, so your focus stays on form and function.
