£4.99The Lunch Break Workout: Effective Training in 30 Minutes or Less
This guide argues against its own title, and that is the point. A 30-minute lunch session is real — it improves strength, interrupts sitting and changes how the rest of the day feels — but the post-meal blood-sugar claim is weaker at lunch than at breakfast, the minimum effective dose is smaller than 30 minutes, and a session does not replace a sedentary rest of the day. The evidence is sound: 2026 dose-response meta-regression (67 studies, 2,058 participants) shows diminishing returns; 2026 split-volume trial (45 men, 8 weeks) shows no detectable strength loss from splitting; 2026 umbrella review (21 RCTs, 921 participants) shows VO2max improves; 2026 circuit-rest study shows shorter rest = higher cardiovascular load, longer rest = more metabolic stress; 2026 meta-analysis shows postprandial exercise is strongest after breakfast and non-significant at dinner. The Template, Four Blocks, 12-week Week ladder, Lunch Timing chapter, and 2-minute Bad-Week Floor are included. Every claim carries its limitation printed beside it.
