Warm-up sets to 225 lb
A simple ramp: the empty bar, then roughly 40, 60, 75 and 85% of your working weight with falling reps, rounded to loads you can build. Rest a minute or two between the heavier ones.
| Set | Weight | Reps | Each side |
|---|
| Warm-up 1 | 45 lb | 10 | Empty bar |
| Work set | 45 lb | – | Empty bar |
Loading the bar like a meet
- Heaviest plates go on first, closest to the collar of the sleeve. Smaller plates sit outside them.
- Colours tell you the weight at a glance on calibrated kilo plates: red 25, blue 20, yellow 15, green 10, white 5.
- Load both sides before lifting. Take the bar off the rack only after the second side is on and clipped.
- Unload one plate at a time, alternating sides, on a bench or squat rack, so the bar does not tip.
