In 1998, California pulled the iron out of its prisons. The people inside got strong anyway — with a floor, a bunk, a chair, a wall, and time. You've got a bedroom. Same equipment. HARD TIME is a six-week bodyweight program built from documented prison training history, run by two coaches who never let you slide: THE LIFER — twenty years of gravel-voiced yard wisdom. Tough as the door, straight as the bars. VOLKOV — quiet, precise, patient as winter. "Pain is weakness saying goodbye." They talk you through every rep — voice coaching with on-screen captions, form cues, rest-break stories from the yard, and drill cadences: DOWN! KICK! PUSH! SNAP! JUMP! AGAIN! THE PROGRAM • 28 workouts across six themed weeks: INTAKE, ROUTINE, YARD TIME, LOCKDOWN, HARD YARD, RELEASE DAY • The Deck — draw cards, pay reps: spades push, hearts sit up, diamonds squat, clubs jumping jack, jokers burpee • Alternating ladders, cell circuits, card squats, iron holds • Daily spread sets — the all-day habit that built yard strength • Every method labeled honestly: documented history or yard legend BUILT FOR A BEDROOM No equipment. No gym. A floor, a bed, a chair, a wall, a towel — that's the whole kit. THE BLOCK ADJUSTS TO YOU Three intake questions place you — Fresh Fish, Gen Pop, or Yard Veteran — and every workout scales to your level. An easier variation is always one tap away, and if life interrupts, your spot's held. FREE. No ads, no accounts, no subscription. Nothing collected, nothing tracked. Ages 13+. The coaches are fictional characters; the training history is real. Not medical advice — consult a physician before starting any exercise program.

Verdict
The clearest difference is in-app purchases: Hard Time at none against Delta's 2. Delta's advantage is update cadence (every 3 weeks vs every 2 months) and device support (3 vs 1). On price, ads and iOS requirement there is nothing between them.
