Frequently Asked Questions
Are medicine balls good substitutes for adjustable dumbbells in HIIT?
Yes—medicine balls are excellent for explosive, rotational and partner moves and offer quick weight changes if you own several sizes. They don’t replicate single-arm press mechanics exactly, so combine them with plates or bands for a fuller strength mix.
Can I use resistance bands instead of dumbbells for HIIT strength work?
Absolutely. Resistance bands provide progressive tension, are very portable and let you do presses, rows and squats. They can feel different from free weights, especially at end-range of motion, but they’re a practical, space-saving option for HIIT.
How do I avoid the smell problem some buyers report with vests and plates?
New-product smells are often from packaging, adhesives or coatings. Air items out in a ventilated space for several days; wipe with a mild detergent or recommended cleaner; follow manufacturer wash/care instructions. If smell persists, use the return policy or contact the seller.
