Short answer: To build a dumbbell set over time, start with one mid weight pair plus the mat you train on, then add a heavier pair every two to three months once you can do 15 clean reps with the heaviest pair you own. Three orders across about six months gives you 2kg, 5kg, 10kg and 15kg pairs for $266 of dumbbells plus a $79 mat, with $0 spent on delivery because every order clears $75.
The three stage plan in short
Staging works here because the pairs are fixed rubber hex weights rather than an adjustable set. You add to the set instead of replacing it, so the 5kg pair you press overhead in week one is still your lateral raise and warm up weight in month nine.
- Stage 1, week 1: PeterMat Zero ($79) and the 5kg pair ($49). Order total $128, delivery free.
- Stage 2, month 3 to 4: 10kg pair ($79) and 2kg pair ($29). Order total $108, delivery free.
- Stage 3, month 6 to 9: 15kg pair ($109). Over $75 on its own, so delivery free.
Stage 1: the first order, week one
Your first order needs one pair you can press overhead for 8 reps and row for 12, and for most people starting out that is the same pair. The 5kg pair at $49 covers goblet squats, rows, presses, curls, lunges and Romanian deadlifts for the first eight to twelve weeks of training.
Buy the mat in this order rather than saving it for later. The PeterMat Zero is 1m x 1m of recycled rubber at 14kg, and at $79 it carries the order past the $75 free delivery threshold on its own, so whatever dumbbell pair goes with it, the first order ships free.
If 5kg is the wrong starting pair
- Too heavy to press: take the 2kg pair ($29) or 3kg pair ($35) first, and the 5kg pair moves into stage 2.
- Already lifting: start at the 10kg pair ($79), then stage 2 becomes the 15kg pair ($109) with a 2kg pair ($29) for shoulder work.
- Not sure: the 5kg pair is the one that stays in use longest, because it keeps working as a warm up weight long after it stops being a working weight.
The 15 clean reps rule: when to place the next order
Order the next pair up when you can complete 15 clean reps of your hardest set with the heaviest pair you own, on two separate sessions in the same week. Clean means full range, controlled on the way down, no swinging, and no stopping mid set to reset your grip.
Fifteen is the trigger because past that point the load has stopped being the hard part. You keep getting fitter, but the pair is training endurance rather than strength.
- Judge it on your strongest lift: Romanian deadlifts and goblet squats reach 15 reps months before overhead presses do, so the squat usually triggers the order.
- Two sessions, not one: a single good day is not a pattern. Hit 15 twice in the same week before you buy.
- Take the real gap: if you are squatting 15 reps with the 5kg pair, the next useful weight is the 10kg pair, not the 4kg pair at $42.
- Order in that week: dispatch is 1-2 business days and metro transit 3-5, so the pair lands while you still want it.
Dispatch is 1-2 business days. Estimated transit is 3-5 business days for metro Australia, 5-10 for regional, 7-14 for remote areas and 7-14 for New Zealand. These are estimates and can vary in peak periods or with carrier delays.
Stage 2: months 3 to 4
The second order does two jobs: it adds a heavier pair for legs and back, and a genuinely light pair for shoulders. The 10kg pair at $79 and the 2kg pair at $29 come to $108 together, so the order ships free.
The 2kg pair is the one people leave out and then order on its own three months later for $29 plus $9.95. Lateral raises, front raises and external rotations all cap out well under 5kg, so adding the light pair here rather than in a fourth order saves the flat rate.
Why 10kg rather than 4kg
The pairs run 0.5kg, 1kg, 2kg, 3kg, 4kg, 5kg, 10kg, 15kg, 20kg and 25kg. The 5kg to 10kg step is the widest gap in the range and it is the one worth taking in a single move for squats, hinges and rows. Your pressing stays on the 5kg pair for a while longer and the rep count carries that progression until the 10kg pair becomes pressable.
Stage 3: months 6 to 9
By the third order you know which lifts you actually do each week. If squats and Romanian deadlifts are the ones hitting 15 reps, the order is the 15kg pair at $109, and at $109 it ships free on its own with nothing added to it.
If your training has moved towards circuits and higher reps instead, spend stage 3 on volume rather than load. The Resistance Bands Set (5-Pack) at $29 plus the Foam Roller (45cm) at $39 comes to $68, which is under $75 and picks up the $9.95 flat rate, so add the 2kg pair at $29 if you skipped it and the order lands at $97 with free delivery.
Stage 3 is also where planning ahead stops being useful. You own four pairs and your own training notes now tell you whether the next buy is the 20kg pair at $139 or nothing at all.
What the full plan costs
| Stage | When | Items | Order total | Delivery |
|---|---|---|---|---|
| Stage 1 | Week 1 | PeterMat Zero, 5kg pair | $128 | Free |
| Stage 2 | Month 3-4 | 10kg pair, 2kg pair | $108 | Free |
| Stage 3 | Month 6-9 | 15kg pair | $109 | Free |
| Plan total | About 6-9 months | One mat, three dumbbell pairs | $345 | $0 |
$345 of gear across three orders, and none of it spent on delivery. Split the same five items into five single item orders and the 5kg pair and the 2kg pair both fall under $75, which adds $19.90 in flat rate charges for nothing in return.
One $345 order ships free too, so staging only buys you cash flow and a few months of not owning pairs you cannot lift yet. If you have the $345 now, one order is simpler.
Keeping every order over $75
Delivery is free on orders over $75 to Australia and New Zealand, and $9.95 flat under $75. A staged plan means more orders, so check the threshold before each one.
- Pairs that clear $75 alone: 10kg at $79, 15kg at $109, 20kg at $139 and 25kg at $169. Order any of these by themselves and delivery is free.
- Pairs that need company: 0.5kg at $19, 1kg at $22, 2kg at $29, 3kg at $35, 4kg at $42 and 5kg at $49. Two of the heavier ones clear the line together, for example 2kg plus 5kg at $78, or 4kg plus 5kg at $91.
- Items that lift a light order over the line: PeterMat Zero at $79, Premium Yoga Mat at $59, Interlocking Foam Tiles (4-Pack) at $65.
- If you are within $15 of $75: adding the Massage Ball Set (3-Pack) at $25 costs you $25 and saves the $9.95, so the net price of the massage balls is $15.05 rather than paying $9.95 for no product.
- Do not buy heavy early to dodge a charge: every pair from 10kg up clears $75 on its own whenever you get to it, so there is no future delivery cost to avoid.
What breaks a staged plan
- Starting with the light pairs: a 1kg pair and a 2kg pair together is $51, which is under $75, and neither stays a working weight for squats or rows past the first fortnight.
- Waiting for boredom rather than reps: boredom arrives well before 15 clean reps does. Track the reps on one lift and let that number decide.
- Closing the 5kg to 10kg gap in small steps: buying the 3kg pair then the 4kg pair to bridge it costs $77 and still leaves you short of 10kg.
- Forgetting the light pair: shoulder and rotator cuff work needs 2kg or less, and that never changes no matter how heavy your squats get.
Storage is the one thing that scales: four pairs is eight dumbbells, and hex heads sit flat against a wall rather than rolling.

$29Frequently Asked Questions
How many dumbbell pairs do I need to start?
One pair is enough to start if it is the right weight, and two pairs cover more lifts without a gap. A 5kg pair at $49 handles squats, rows, presses and lunges for the first eight to twelve weeks for most beginners. A 10kg pair at $79 added around month three is the point where leg and back work stops being limited by the weight.
When should I buy the next heaviest dumbbell pair?
When you can do 15 clean reps of your hardest set with your current heaviest pair, on two separate sessions in the same week. Clean means full range with control on the way down and no swinging. Place the order that week, because orders are processed within 1-2 business days and metro Australian transit is another 3-5 business days.
Is it cheaper to buy a dumbbell set all at once or over time?
The dumbbells cost the same either way, because every pair is priced individually and there is no bundle discount. Staging only costs more if an order slips under $75, since orders under $75 pay a $9.95 flat rate while orders over $75 ship free to Australia and New Zealand. Keep each staged order over $75 and the two approaches cost exactly the same.
What weights should my first three orders cover?
A 5kg pair with a mat first, then a 10kg pair alongside a 2kg pair, then a 15kg pair. That gives you 2kg, 5kg, 10kg and 15kg for $266 of dumbbells spread across three orders, and each order clears the $75 free delivery threshold on its own.
Do the dumbbells I buy first become useless later?
No, because these are fixed rubber hex pairs rather than an adjustable set, so each new pair adds to what you own. A 5kg pair you press overhead in your first month becomes your lateral raise weight and your warm up weight once you are pressing the 10kg pair.
Can I keep delivery free on every order in a staged plan?
Yes, as long as each order is over $75. The 10kg ($79), 15kg ($109), 20kg ($139) and 25kg ($169) pairs clear that on their own. Lighter pairs need a second item in the order, and the PeterMat Zero at $79, Resistance Bands Set at $29 or Massage Ball Set at $25 are the usual ways to do it.
How long does each order take to arrive?
Orders are processed within 1-2 business days and a tracking number is emailed once your order ships. Estimated transit is 3-5 business days for metro Australia, 5-10 business days for regional Australia, 7-14 for remote areas and 7-14 for New Zealand. Those are estimates and can vary in peak periods or with carrier delays.
