How Rackd picks your next weight

You log a set. The app stores the weight, the reps, and the RPE if you tagged one. Next time the same lift comes up, Rackd already knows what to load. No guessing, no spreadsheet, no math at the rack.

Here is what is happening underneath.

The rule lives on the program

Every program in Rackd runs on one of 11 progression systems. The system is part of the program. When you add 5/3/1 to My Rack, you are also picking 5/3/1's training-max progression. When you add 5x5, you are picking linear add-the-bar. Custom programs let you pick the system in the builder.

The 11 systems cover the patterns that actually work in a gym: linear, double progression, wave, percentage-of-max, training-max with cycles, RPE auto-regulation, AMRAP-driven, rep-target, time-under-tension, ladder, and bodyweight-rep progression. Different programs lean on different ones for different lifts.

What Rackd reads

Three things drive the next number.

• Last session result. Did you hit the prescribed reps on every set, or did the last set fall short? A clean session moves the weight up. A short session holds or backs off, depending on the rule.
• RPE, if you logged one. RPE 7 means three reps in the tank. RPE 10 means none. The progression rules that use RPE will push harder when the bar moved fast and pull back when it ground.
• Where you are in the cycle. Programs with weeks built in (5/3/1, block periodisation, wave) know whether this is a heavy week, a volume week, or a deload. The next weight comes from the cycle, not from yesterday.

What you see at the rack

The next session screen shows the working weight, the rep target, and the warm-up ramp. Tap Start, the timer runs the rest, the next set is queued. If the rule called for a deload, the screen says deload. If a training max moved, you see the new number on the program card before you start.

You do not type a percentage. You do not check a sheet. You show up, the bar is loaded for you, and the rule does the rest.

Load the bar.
