Frequently Asked Questions
Can I sprint safely with a weighted vest?
Yes—if the vest fits snugly and weight is distributed close to your torso. Use lower loads for maximal sprints, ensure the vest doesn’t shift, and progress weight gradually to avoid changes in sprint mechanics.
Are sand-filled vests better than packet-style weights for HIIT?
Sand-filled vests often sit lower-profile and feel more like a single piece—good for steady runs and tempo work. Packet-style systems offer modularity that’s useful when you need quick weight changes between circuits or progressive loading.
How do I reduce the smell from a new vest?
Air the vest outside for several days, wipe internal surfaces with a mild detergent solution, then let it dry fully. Some users also store new vests in a ventilated area for a week; persistent odors should be addressed via the seller warranty.
