Frequently Asked Questions

Tabata is a form of high-intensity interval training — 20 seconds of maximum effort followed by 10 seconds of rest, repeated across multiple sets — scientifically shown to improve both aerobic and anaerobic fitness more efficiently than steady-state cardio.

The original 1996 research by Dr. Izumi Tabata found that this protocol improved VO₂ max (the body's ability to use oxygen) by up to 15% in just six weeks. The short rest window keeps your heart rate elevated, burning more calories and driving adaptation faster than longer, lower-intensity sessions.

Three days a week is the sweet spot where science and real life meet — research consistently shows it produces the same muscle and strength gains as training six days a week when total weekly volume is matched, while giving your body 48–72 hours to recover and actually grow between sessions.

More isn't always better. Muscle protein synthesis — the repair process where muscles rebuild stronger — stays elevated for roughly 24–72 hours after a session. Training again before that window closes can interrupt recovery rather than accelerate it. Three days lets you hit each muscle group enough to drive adaptation without accumulating fatigue that erodes performance.

It also fits the rest of your life. A sustainable three-day routine beats an ambitious five-day plan you can't stick to.

Fewer, controlled reps with proper load means more time under tension per rep — and that's where the real stimulus for growth comes from.

Time under tension (TUT) refers to how long your muscles are under load during a set. When you slow down and control each rep through its full range of motion, you recruit more muscle fibres and increase metabolic stress — both key drivers of hypertrophy. A study published in the Journal of Physiology found that greater time under tension significantly elevated myofibrillar protein synthesis (the process that builds contractile muscle tissue) in the 24–30 hours following exercise.

In practice: 8 slow, controlled reps with good form creates a stronger growth signal than 15 rushed reps where momentum does half the work. It also reduces injury risk by keeping joints loaded in a controlled manner throughout each movement.

The founder. The presets reflect how he personally likes to train — a favourite combination of compound movements across push, pull, and legs that has worked for him across gyms, hotel rooms, and everything in between.

Because working out shouldn't require a whiteboard, a stopwatch, and a notepad. noBS was built out of frustration with clunky checklists, missed set counts, and the mental overhead of trying to structure a workout while actually doing one.

One app. Full structure. No streaks, no subscriptions, no guilt. Just a timer that keeps you honest and lets you focus on the work.
