reckonerDumbbell bench press
The same press with two independent weights, which is harder than it sounds. Each arm carries its own load, so a side that has been quietly coasting has nowhere to hide, and the bells can travel further than a bar ever could.
Lower the bells to chest depth.

How to do it
Get them up without a fight
Sit on the end of the bench with a bell resting on each thigh. Lie back and kick your knees up one at a time, so the bells arrive over your chest instead of being hauled there by the shoulders.
Set the back
Shoulder blades together and down into the bench, feet flat on the floor. The set-up is the barbell set-up and it matters more here, because nothing is holding your two hands in line with each other.
Lower to chest depth
Bring the bells down until your upper arms are roughly level with your torso, elbows at about sixty degrees. Deeper is not better once the shoulder starts rolling forwards.
Press, and let them come together
Press up and slightly in. The bells finish close together but never touch: banging them at the top is a rep that stopped being under control.
What goes wrong
Letting one arm lead
The stronger side finishes first and the weaker one drifts. Match the tempo to the slower arm, because that is the arm the weight is actually chosen for.
Turning it into a fly
Elbows wide and bells looping out to the sides is a different exercise with a much longer lever, and the shoulder pays for it. Keep the forearms vertical.
Dropping the bells to get out
Bring your knees back up, sit forward, and set them down. Dumping them from the top is how bells get chipped and floors get cracked.
How Reckoner progresses this lift
Six weeks of this lift, from 22 kg, run through the real engine. Nothing below was typed in: the prescription, the decision and the sentence beside it all come from the same code that writes your week.
| Week | Prescribed | What it did |
|---|---|---|
| 1 | 4 x 6 at 22 kg | More reps 6 → 7 repsRPE 7.5 with room left in the range, so reps climb before the load does. |
| 2 | 4 x 7 at 22 kg | More reps 7 → 8 repsRPE 7.5 with room left in the range, so reps climb before the load does. |
| 3 | 4 x 8 at 22 kg | Deload 40% of sets offThree weeks of building, then one week lighter. About 40% of the sets come off. The load holds and your reps stay where you earned them, so you keep the strength and lose the fatigue. |
| 4 | 2 x 8 at 22 kg | More reps 8 → 9 repsRPE 7.5 with room left in the range, so reps climb before the load does. The lighter week is over, so this is back to four sets. |
| 5 | 4 x 9 at 22 kg | More reps 9 → 10 repsRPE 7.5 with room left in the range, so reps climb before the load does. |
| 6 | 4 x 10 at 22 kg | Load up 22 kg → 24 kgYou hit the top of the range at RPE 7.5, so the bar goes up 2 kg to 24 kg and reps reset to six. |

Questions people ask
Should the weight be per dumbbell or the pair?
Per dumbbell. Reckoner prescribes and records the weight of one bell, which is what is written on the one you pick up.
Why does it climb in a different step from the barbell?
Because a dumbbell rack and a barbell are stocked differently, and the step has to be a weight you can actually pick up. Reckoner asks each movement what its own gym holds rather than adding a percentage that leaves you standing at a rack with nothing to reach for. The step for this one is in the fact block above.
Is it a good swap for the barbell bench press?
It is the swap Reckoner offers first when the barbell version stalls, when a shoulder does not like the fixed bar path, or when there is no rack free.
