Adaptive Training, Drill Sergeant, and the Study Module

Exercise selection has been completely rebuilt from scratch. Gone is the random picker. In its place: a 10-tier difficulty progression that adapts to your performance. Exercises get harder as you improve, with separate tracking per exercise across tiers.

You also now pick a fitness goal — beginner, fat loss, general, muscle building, strength, time efficient, intermediate, or athletic. Each goal has its own modifier pipeline that reshapes exercise distribution, rep targets, and round structure. A beginner session feels completely different from a strength one.

Completely new workout mode. Instead of getting a random exercise each time you die, Drill Sergeant plans your entire session upfront. Before your match starts, it generates a full workout based on your goal, equipment, and fitness level. You preview every round, see which exercises are coming, and approve the plan.

Then it executes as a flat queue: each CS2 death serves the next exercise in order. A progress bar shows exactly how far through you are. When the queue runs out, bonus rounds kick in with lighter exercises.

This one's nerdy. Killogram now tracks fatigue across 20 individual muscles using a bi-exponential recovery model. A fast metabolic component (8-hour half-life) for ATP and glycogen recovery, and a slow structural component (20–42 hours depending on muscle size) for protein synthesis and damage repair.

The training preview shows a muscle map with real recovery data. The exercise engine penalises fatigued muscles and favours fresh ones, so you stop accidentally hammering your chest three days in a row.

Every exercise now has a cardio intensity rating. Credit is split between muscle work and cardio work, tracked separately. Your weekly cardio target adjusts per fitness goal, and the training preview shows cardio progress alongside strength buckets.

All 12 cardio exercises are now timed with duration progressions instead of rep counts. If a muscle group hasn't recovered between queue exercises, you get a mobility or cardio filler instead of an exercise that'll just hurt you.

Weighted exercises now track your current load in lbs or kg. Weight auto-initialises from equipment defaults and adjusts based on perceived effort — too easy bumps up, too hard drops down. A weight badge on exercise cards means you always know what you're about to lift.

OK this is a left turn. Killogram now has a GCSE revision module. Spaced repetition flashcards across 15 subjects, powered by the FSRS algorithm (same one behind Anki). Multiple card types: multiple choice, ordering, and matching pairs.

There's also an AI tutor powered by Google Gemini, with specialist teacher personas for Maths, Chemistry, Biology, Physics, and Computer Science. Each one tracks your mastery and can spot common misconceptions. It's in beta — we're still working out the kinks — but the core loop is solid.

With three modules now (fitness, gaming, learning), the app needed a proper colour language. Emerald for fitness, cyan for gaming, violet for learning. Consistent typography with Tomorrow for headings and Aldrich for section titles. A proper component library with cards, buttons, and badges that look right everywhere.
