Skipping the gym for a week is way less bad than skipping your morning coffee—if you're a regular drinker.
A week off training? Science says you won't lose real muscle or strength. Any "flat" look is just less glycogen and pump, not atrophy. Gains start fading only after 2-3 weeks of total inactivity. A short break can even help recovery, joints, and motivation. You'll bounce back fast.
Skipping coffee? That's rough for most people. Caffeine withdrawal hits in 12-24 hours: pounding headaches, fatigue, irritability, trouble focusing, and that zombie-like fog. It can mess with your whole day—work, mood, energy—for 2-9 days. Not dangerous, but honestly miserable.
Bottom line: Your body forgives a gym break quickly. Your brain's adenosine receptors? Not so much. If you must skip one, let the weights rest and grab that cup. Consistency in training matters more long-term anyway.
