Weights are rounded to what you can load with standard plates on a 20 kg bar.

Load the working set

How the ramp is built

Each warm-up set is a fixed percentage of your working weight, with reps tapering as the weight climbs. The default three-set ramp runs 40% × 10, 60% × 6, 80% × 3 — enough exposure to groove the movement without accumulating fatigue that costs you working-set reps.

With five sets the ramp starts lighter (30%) and climbs in smaller jumps to 85%; with one or two sets it starts at 50%. Pick more sets for heavy top sets or the first lift of a session, fewer for accessories when you are already warm.

Why the weights look rounded

For barbell lifts, every suggested weight is rounded to something you can actually load with standard plates — the same greedy plate math as the plate calculator. For dumbbell and machine exercises, weights round to the nearest 2.5 kg or 5 lbs instead.

Warm-up principles

Gript builds this exact ramp inside your workout and inserts the sets with one tap, already marked as warm-ups so they never skew your volume.

Frequently asked questions

How should I warm up before a heavy set?

Ramp up in 3–5 sets: start light around 40–50% of your working weight for higher reps, then increase the weight while cutting reps each set — for example 40% × 10, 60% × 6, 80% × 3. The goal is to prepare the movement without accumulating fatigue.

How many warm-up sets do I need?

Three sets works for most working weights. Use more sets (4–5) for very heavy top sets or first thing in a session, and fewer (1–2) for later exercises when the muscles are already warm.

Should warm-up sets count toward my training volume?

No. Warm-up sets are deliberately submaximal, so counting them inflates your volume numbers. Mark them as warm-ups in your log — Gript excludes warm-up sets from volume automatically.

Why do the suggested weights look rounded?

For barbell lifts the calculator rounds each set to a weight you can actually load with standard plates on your bar. For dumbbell and machine exercises it rounds to the nearest 2.5 kg or 5 lbs.
