Short answer: The 20kg rubber hex dumbbell pair is $176 AUD including GST, for two 20kg dumbbells (40kg in total). Delivery is priced by your postcode in the cart, and you see the exact cost before paying.
The 20kg pair: price and what you get
It is built for experienced lifters: heavy goblet squats, Romanian deadlifts, floor or bench presses and loaded carries. This is the pair that keeps a dumbbell only program progressing into its second year.
- Weight: 20kg per dumbbell, 40kg for the pair.
- Head: cast iron sealed in a moulded rubber shell.
- Shape: hexagonal and anti-roll.
- Handle: knurled chrome.
- Price per kg: $4.40, the lowest of any pair in the range.
Why the price per kg is the lowest in the range
The 20kg pair costs $6 more than the 15kg pair and $108 less than the 25kg pair. Here is how the heavy pairs compare on goods price alone.
| Pair | Price | Total weight | Price per kg |
|---|---|---|---|
| 10kg | $114 | 20kg | $5.70 |
| 15kg | $170 | 30kg | $5.67 |
| 20kg | $176 | 40kg | $4.40 |
| 25kg | $284 | 50kg | $5.68 |
If you are deciding between 15kg and 20kg and both are usable for you, the 20kg pair gives you 10kg more iron for $6. Delivery adds a few dollars on top, about $2 more to Sydney and about $6 more to Melbourne than the 15kg pair.
What it costs delivered
Delivery is charged per item from your postcode. A 40kg pair is a heavy parcel, so freight varies more by state than it does for light pairs. These are examples; the cart shows your exact figure.
| Area | Delivery, about | 20kg pair delivered, about |
|---|---|---|
| Sydney | $22.39 | $198 |
| Melbourne | $35.61 | $212 |
| Brisbane | $38.66 | $215 |
| Adelaide | $41.71 | $218 |
| Perth | $75.28 | $251 |
| Canberra | $35.61 | $212 |
| Hobart | $98.68 | $275 |
| Regional QLD | $78.34 | $254 |
Regional and remote areas cost more, and a few items cannot be sent to remote postcodes. The cart tells you if yours is one of them.
Who a 20kg pair suits
- Lifters whose legs have outgrown 15kg: 20kg goblet squats and a 40kg Romanian deadlift keep lower body work in the 8 to 12 rep range.
- People returning to training after a gym membership: if you have squatted and deadlifted a barbell before, 20kg is often the first pair that feels like work.
- Anyone doing heavy carries: 20kg per hand over 30 to 40m loads grip, traps and core hard.
- The one heavy pair in a two pair setup: with a 10kg pair, $290 for both, you cover presses and accessories with the 10kg and legs and back with the 20kg.
Who should pick a different pair
- You have not lifted before: the 10kg pair at $114 is the place to start. 20kg is heavy enough to make poor form on a deadlift risky.
- You cannot row 15kg for 8 clean reps: the 15kg pair at $170 fits better, even though the 20kg pair is better value per kg.
- You want a pair for overhead pressing: most people press 10kg to 15kg dumbbells overhead. 20kg overhead is an advanced lift.
- You live up several flights of stairs with no lift: the box is 40kg plus packaging. Plan the carry, or open it at the door and carry the dumbbells up one at a time.
Exercises and rep ranges for 20kg
| Exercise | Sets and reps with 20kg | Notes |
|---|---|---|
| Goblet squat | 4 x 6-10 | Hold the top head with both hands |
| Romanian deadlift | 4 x 8-10 | 40kg total, keep the dumbbells close |
| Bulgarian split squat | 3 x 6-8 each leg | Rear foot on a sturdy chair |
| Single arm row | 4 x 8-10 each side | Brace on a bench or chair |
| Floor press | 3 x 6-10 | Pause on the floor each rep |
| Farmer carry | 4 x 30m | Short steps, chest up |
| Dumbbell deadlift | 3 x 8-10 | Dumbbells beside the feet, flat back |
Rest 2 minutes between sets of squats and deadlifts, and 90 seconds elsewhere. Warm up with two lighter sets first; a 10kg pair suits that.

When to move up from 20kg
20kg lasts a long time for rows and presses. Goblet squats run out first, partly because a 20kg dumbbell becomes awkward to hold at the chest well before your legs reach their limit.
- Before buying anything: switch goblet squats to Bulgarian split squats. Each leg works alone, so 20kg feels a lot heavier.
- Slow the lowering: a three second lower on Romanian deadlifts adds work for free.
- Then add weight: the 25kg pair is $284. It is the heaviest pair in the range, and past it a barbell is the usual next step.
Delivery timing and floor protection
Orders usually dispatch within 1 to 3 business days, and metro deliveries usually arrive 2 to 7 business days after dispatch. Regional and remote areas take longer. See the shipping page.
Train on a 10 to 15mm rubber gym mat. Set the dumbbells down under control; a 20kg dumbbell dropped onto tile or a floating floor can damage it. The floor protection guide compares the options.
