Compare the 2.5kg and 20kg hex dumbbell pairs from Northern. Learn which weight suits your home gym goals, from light toning to heavy strength training.
Quick answer
Choose the 2.5kg pair for low-impact toning, rehab, or light workouts; pick the 20kg pair for serious strength building and progressive overload.
Weight difference and training purpose
The 2.5kg x2 (5kg total) pair is ideal for beginners, seniors, or anyone focusing on high-rep endurance, warm-ups, or rehabilitation. The 20kg x2 (40kg total) pair targets intermediate to advanced lifters looking to build muscle and strength with compound movements like rows, presses, and squats.
Because the 20kg pair is eight times heavier, you cannot use it for the same exercises as the 2.5kg pair. That weight jump means you need proper form and a solid fitness base before progressing.
Grip and handle design
Both pairs share the same ergonomic chrome handle with a knurled grip. The knurling provides a secure, slip-resistant hold during sweaty sessions. The handle diameter is consistent across weights, so switching between pairs does not require adjusting your grip technique.
Price and value for money
The 2.5kg pair is priced at USD 21.69 (compared to USD 34.99), making it an affordable entry point. The 20kg pair costs USD 89.69 (compared to USD 137.99), offering significant savings per kilogram. If you plan to build a full set, starting with the heavier pair gives more long-term value for strength training.
Trade-offs at a glance
- 2.5kg x2 (5kg total): Best for light toning, warm-ups, rehab, and high-rep endurance work. Very affordable at USD 21.69. Not suitable for building significant muscle mass.
- 20kg x2 (40kg total): Best for strength training, compound lifts, and progressive overload. Priced at USD 89.69 with good per-kg value. Too heavy for beginners or rehab.
- Compatibility as a set: If you buy both pairs, you cover a wide range from light to moderate weight. However, the 18.5kg gap between them means you may want an intermediate weight (e.g., 10kg or 12.5kg) for smooth progression. Consider adding a mid-range pair for gradual weight increases.
