Short answer: The 15kg rubber hex dumbbell pair is $170 AUD including GST, for two 15kg dumbbells (30kg in total). Delivery is priced by your postcode in the cart, and the exact cost shows before you pay.
The 15kg pair: price and what you get
This is the intermediate pair: rows, presses, lunges and deadlifts once 10kg feels easy. With a 10kg pair beside it, the two cover a full strength program for most people for a year or more.
- Weight: 15kg per dumbbell, 30kg for the pair.
- Head: cast iron sealed in moulded rubber.
- Shape: hexagonal, so the dumbbells stay put between sets.
- Handle: knurled chrome, which helps grip on heavy rows and carries.
- Price per kg: $5.67.
What it costs delivered
Delivery is charged per item from your postcode. A 15kg pair costs more to send than a 10kg pair because of the weight. Examples for metro postcodes are below; the cart shows the exact figure.
| Area | Delivery, about | 15kg pair delivered, about |
|---|---|---|
| Sydney | $20.35 | $190 |
| Melbourne | $29.51 | $200 |
| Brisbane | $32.56 | $203 |
| Adelaide | $34.59 | $205 |
| Perth | $62.06 | $232 |
| Canberra | $29.51 | $200 |
| Hobart | $81.39 | $251 |
| Regional VIC | $49.85 | $220 |
Regional and remote areas cost more than metro, and a few items cannot be sent to remote postcodes. The cart tells you before you pay.
15kg or 20kg: check this first
The 20kg pair is $176, only $6 more than this pair, and at $4.40 per kg it is the cheapest per kg in the range. Delivery is a little higher: about $22.39 to metro Sydney and about $35.61 to metro Melbourne.
| 15kg pair | 20kg pair | |
|---|---|---|
| Price | $170 | $176 |
| Total weight | 30kg | 40kg |
| Price per kg | $5.67 | $4.40 |
| Delivered to Sydney, about | $190 | $198 |
| Delivered to Melbourne, about | $200 | $212 |
| Delivered to Perth, about | $232 | $251 |
Price is a poor reason to buy weight you cannot use. Pick 15kg if you can row and press 15kg for 8 good reps but not 20kg. Pick 20kg if 15kg goblet squats and Romanian deadlifts would already be easy. If you will only ever own one heavy pair and your legs are strong, the 20kg pair gives you more room to progress.
Who a 15kg pair suits
- Intermediates who have outgrown 10kg: once 10kg goblet squats pass 15 reps, 15kg is the next step.
- Active men and returning lifters: 15kg is a common first heavy pair for rows, floor presses and lunges.
- People adding farmer carries: 15kg in each hand loads grip and upper back hard over 30 to 40m.
- The heavy half of a 10kg plus 15kg setup: $284 for both pairs.
Who should pick a different pair
- You have not trained with weights before: start with the 10kg pair at $114. 15kg overhead is out of reach for most beginners.
- You want the pair for shoulders and arms: 15kg lateral raises are beyond most people. A 5kg pair ($48) does that job.
- Your legs are already strong: look at the 20kg pair, for the reasons in the comparison above.
The rule from the weight guide applies: if 12 clean reps of your main exercise are hard on the last two, the weight is right. Fewer than 8, go lighter. More than 15 easy reps, go heavier.
Exercises and rep ranges for 15kg
| Exercise | Sets and reps with 15kg | Notes |
|---|---|---|
| Goblet squat | 4 x 8-12 | Elbows inside the knees at the bottom |
| Romanian deadlift | 3 x 8-12 | 30kg in your hands, hinge at the hips |
| Reverse lunge | 3 x 8-10 each leg | Dumbbells at your sides |
| Single arm row | 3 x 8-10 each side | Pull to the hip, pause |
| Floor press | 3 x 8-10 | Pause with elbows on the floor |
| Farmer carry | 3 x 30-40m | Stop when grip slips |
| Single leg Romanian deadlift | 3 x 8 each leg | One dumbbell in the opposite hand |
A four day upper and lower split

When to move up from 15kg
- Goblet squats and Romanian deadlifts pass 12 slow reps: add the 20kg pair at $176.
- Rows pass 12 reps: slow the lowering to three seconds first, then move rows to 20kg.
- Presses: most people press 15kg for a long time, so keep the pair for upper body work after the 20kg pair arrives.
The progressive buying plan covers the order to add pairs beyond 15kg.
Delivery timing and storage
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. Details are on the shipping page.
The box is 30kg plus packaging, so plan the carry if you live up stairs. Store the pair on the floor or on a shelf rated well above 30kg, and train on a 10 to 15mm rubber gym mat. Rubber heads set down under control will not mark the floor, but a dropped 15kg dumbbell can crack tile.
