Every exercise in SnaqBreak™ carries an evidence grade based on verified research. This page documents the physiological mechanisms, the peer-reviewed studies, and the rationale behind every snaq.
Belief isn't just a psychological state — it's a biological variable. In 2007, Harvard researchers informed hotel housekeepers that their daily physical work met clinical guidelines for active living. Within four weeks, the informed group showed measurable drops in weight, blood pressure, and body fat, despite making zero changes to their actual behavior. Cognitive appraisal changed how their bodies responded to existing movement.
But context is only half the equation. Frequency is the other. A 2013 study demonstrated that breaking up sedentary time with light movement throughout the day improves insulin sensitivity and lipid profiles significantly more than a single hour of intense exercise. A one-hour gym session cannot undo the metabolic cost of sitting all day.
This is why SnaqBreak doesn't just give you a timer. Every snaq combines a studied physiological mechanism with a scheduled reminder to actually do it — so your body gets both the signal and the nudge.
The informed housekeepers lost weight and reduced blood pressure with zero behavior change. The only variable was knowing their work counted. A separate study found that frequent light movement across the day outperforms a single workout for insulin and lipid control. Both studies point to the same conclusion: how and when you move matters as much as whether you move.
"SnaqBreak doesn't just tell you to move. It tells you why this movement, right now, matters for your body — and then reminds you to do it again. The science says that changes everything."
Every exercise in SnaqBreak carries one of three evidence grades. Each grade reflects two things simultaneously: the strength of the research supporting the health claim, and the confidence in the step-equivalent calculation. A higher grade means greater certainty about both what the exercise does and how to quantify it.
Direct snaq-specific research from a landmark RCT or large-scale observational study, combined with a directly measured MET value from the 2024 Compendium of Physical Activities.
Well-designed studies — but either the research tests a related movement category rather than this exact exercise, or the MET value is inferred from the closest Compendium category.
Limited snaq-specific research and/or MET value estimated from a general Compendium category. The benefit is plausible and consistent with established exercise science.
Step counters detect wrist movement and foot strikes — which means any exercise that doesn't involve locomotion goes unrecorded. A wall sit, a plank, soleus push-ups — all register zero regardless of the metabolic effort involved.
SnaqBreak converts the intensity of each exercise into step equivalents using verified MET values from the 2024 Compendium of Physical Activities.
The constant 28 is derived from the standard steps-per-minute of brisk walking calibrated to step-count research norms. MET values marked "est." are inferred from the closest 2024 Compendium category.
We measure snaqs in steps because everyone understands steps. But what you're really building is stable blood sugar, a stronger heart, and a body that doesn't crash by 3pm.
| Exercise | Duration | MET | Calculation | Steps |

| Soleus Push-ups | 1.0 min | 2.8 est. | 1.0 × 2.8 × 28 | 78 |
| Jump Rope | 1.0 min | 11.8 | 1.0 × 11.8 × 28 | 330 |
| Jumping Jacks | 1.0 min | 7.5 | 1.0 × 7.5 × 28 | 210 |
