SNODE 8 Pieces Magnet Weight Plates

These 1.25 lb magnet plates are designed to increase resistance on iron and cast iron dumbbells. They attach via magnetic adsorption, allowing controlled microloading without changing the bar or end caps. The set comprises eight plates, providing precise 1.25 lb increments per side. Caution is advised on non-magnetic surfaces to prevent slippage. Ideal for incremental strength work and compatible with various iron dumbbells and Smith machines for versatile workouts.
Platemate 1.25 lb Donut Pair

The Platemate donut pair provides two 1.25 lb magnetic add-ons, offering a 2.5 lb total increase when attached to a dumbbell ends. This small, circular design is intended for safe microloading and space-saving storage. The magnets enable quick attachment and release, making it suitable for progressive workouts across beginner, intermediate, and advanced levels. Use on iron or steel dumbbells and barbells to achieve steady weight progression without buying new dumbbells.
SNODE AD80 Cast Iron Adjustable Dumbbell Set

This SNODE set expands an adjustable dumbbell to 90 lbs by adding eight 1.25 lb magnet plates, enabling weight increments of 2.5 lb and 5 lb. The dial-based adjustment allows rapid changes, and the plates are calibrated for consistent increments. The configuration supports balanced loading on both sides, making it suitable for compound lifts and unilateral movements alike. It is especially useful for users who want finer control over weights without purchasing multiple pairs of dumbbells.
Mid Weights Silicone Microweights

These 1.25 lb silicone-encased micro weights are designed for precise insertions on many dumbbells. The set includes four pieces with a tolerance of ±6 grams, aiming for stable, secure fits on most ends. The silicone outer shell helps protect the dumbbell end caps while offering a smooth profile for a minimal protrusion during movement. A flexible attachment design supports reliable use across a variety of grip styles and exercises.
Buying Guide
- Weight increments: Choose add-ons with 1.25 lb or 2.5 lb increments to align with progressive overload goals and your current dumbbell set.
- Compatibility: Verify compatibility with your specific dumbbell type (iron/cast iron vs. rubber ends) and surface material to ensure secure attachment.
- Attachment method: Magnetic designs offer quick changes but require ferrous surfaces; silicone-encased or clip-on options may provide more universal compatibility but vary in ease of use.
- Durability and material: Steel or high-strength alloys with protective coatings hold up to regular training and minimize wear on dumbbell ends.
- Safety and stability: Ensure the add-ons stay in place during dynamic movements; avoid on surfaces prone to detachment or slippage.
- Storage and space: Microweights save space compared with full weight sets, beneficial for home gyms or travel-ready setups.
- Budget and value: Compare per-pound cost and the number of pieces included to determine overall value for your training plan.
- Warranty and support: Check manufacturer guarantees and replacement policies if a plate or magnet loosens over time.
- Usage scenarios: Consider how you will use the add-ons (isolation work, progressive overload, rehabilitation) to select the most versatile option.
- Maintenance: Periodically inspect magnets and fittings for corrosion or wear; clean following user guidelines to maintain adhesion.
