Whether you want to make bodyweight moves harder, increase calorie burn during runs, or add progressive resistance to circuits, the RUNmax Runfast Pro (RM20WP) gives you a straightforward way to dial intensity up or down. Built from tear-resistant nylon with removable weight packs and an adjustable fit, this 20 lb vest suits a wide range of training styles and body types. A lifetime warranty backs the vest, so it’s intended as a long-term addition to your kit.
The vest increases external load without changing your movement patterns, so the same squats, push-ups, or runs feel more challenging. Because weights are removable, you can progress gradually and tailor resistance to each session.
Design choices focus on mobility and comfort: the vest leaves the arms free, uses an adjustable strap system for a secure fit, and distributes load across the torso so strain on shoulders and lower back is minimized. The tear-resistant nylon exterior holds up to repeated use in the gym or outdoors.
Changing the vest’s load is quick: remove or insert weight packs to match the workout’s goal, from light overload for running to heavier resistance for strength sessions. The strap system and sizing accommodate both men and women and allow you to tighten the vest so it stays stable during sprints or plyometrics.
Cleaning and upkeep are straightforward—wipe the exterior with a damp cloth and air-dry to keep the fabric in top condition. RUNmax includes a lifetime warranty, offering long-term support and confidence that the vest is built to last.
Who is this for: The RUNmax Runfast Pro 20 lb vest is designed for athletes, fitness enthusiasts, and anyone wanting to safely increase training intensity—perfect for runners adding resistance, lifters seeking extra load during bodyweight exercises, or coaches building progressive conditioning programs. If you need an adjustable, durable vest that fits multiple body shapes and training styles, the RM20WP is a versatile, long-lasting option.
Q: Can I remove weights to reduce load?
A: Yes. The removable weight packs let you quickly reduce or increase resistance for different sessions.
Q: Will this vest fit my body size?
A: Yes. Adjustable straps and a universal cut are designed to fit a wide range of body shapes securely.
