Items that say "You need to work out."
Perhaps you want to give your friend a glimpse into CrossFit, the discipline that has changed your life (and put an ache in your hamstring). Or your sister's been curious about Flywheel indoor cycling, so you opt to gift her a few of the pricey classes? Well meaning, yes; doomed, oh yes. This gift sends one of two messages: You need to lose weight and get healthy, which unhealthy people already know and feel bad about; or, best case, the recipient is moderately grateful, but still considers it the least confidence-inspiring present they got all year. Only the most ripped Ironmen among your family and friends will be thrilled to receive extra training for free, while everyone else will feel hurt or resentful at best.
