Warm-Up Set Calculator

The warm-up calculator produces a series of progressively heavier sets that prepare your body for the workout. Enter your working weight below, and the calculator will produce a warm-up series ramp with suggested repetition rates and plate loads for each series.

Why warm-ups matter

Warm-up sets have three functions:

Tissue preparation. Progressive loading increases blood flow to muscles, tendons and ligaments. Warm tissue is more flexible and less prone to injury. This is not optional - it's the price of decades of safe exercise.

Movement pattern training. Every warm-up is an opportunity to hone your movement pattern before the load makes compensation costly. Your first heavy repetition should feel like the twentieth repetition of the day, not the first.

Hermal system activation. Heavy loads require maximum recruitment of motor units. Working through progressively heavier sets activates the neural pathways you need for the working sets. Jumping straight to heavy weights leaves recruitment capacity unused.

How to get up to working weight

A good warm-up follows a simple structure: start with an empty bar, increase in roughly equal increments, and decrease reps as the weight increases.

Example: working weight 140 kg (squat).

| Series | Weight | Repetitions | Repeats | |---|---|---| | 1 | 20 kg (bar) | 10 | | 2 | 60 kg | 5 | | 3 | 80 kg | 4 | | 4 | 100 kg | 3 | | 5 | 120 kg | 2 | | 6 | 140 kg | Working sets |

The jumps do not have to be perfectly flat. They must be gradual enough so that no jump feels jarring.

Rules of thumb

Always start on the bar. Always. It costs 30 seconds and lays the groundwork for the movement pattern.

Do bigger jumps early, smaller jumps late. A jump from 20 to 60 is good. A jump from 120 to 160 is too big. Narrow the gaps as you approach the working weight.

Drop reps as the weight increases. Warm-ups should prepare you, not tire you. When you're at 80-90% of your working weight, single or double weights are sufficient.

Rest between heavier warm-up sets. The first sets don't need rest. Above 70% of your working weight, hold for 60-90 seconds. Your last warm-up set should feel fresh, not rushed.

Common mistakes

Skipping warm-ups altogether. Some lifters walk in, load their working weight and leave. This works until it doesn't, and the failure mode is an injury that costs months.

Too many warm-up sets. The opposite extreme. Fifteen warm-up sets in 30 minutes is a waste of energy and time. Four to six sets is the best option for most working weights.

Overly high repetition rates for heavy warm-up sets. Doing five reps at 90% of the working weight is a working set, not a warm-up. Keep the last 2-3 warm-up sets to 1-3 reps.

Warm-up for isolation work. You don't need a warm-up ramp for biceps. Warm-up protocols are for compound weight movements. If you've already done compound exercises, your body will be warm.

You use the same warm-up regardless of the work weight. Your warm-up for a 60 kg bench and 140 kg squat should not have the same number of sets. Heavier work weights need more lifting sets.

General vs. specific warm-up

The counter above deals with a specific warm-up - the bar ramp. Before that, 5 minutes of general activity (rowing, cycling, band training) can be helpful, especially if you are training in the cold or early morning. Keep it short. The dumbbell warm-up is what really prepares you for dumbbell work.

Enter your working weight above and you'll get your warm-up plan.
