A peculiar new fitness trend has emerged in 2026, with runners taking up butter-making during their jogs. Content creator Libby Cope and her partner have popularised the practice, which involves pouring cream and salt into double-bagged zip-lock sandwich bags, placing them in backpacks, and shaking them while running. After a few miles, the cream transforms into butter.
According to Runners World, the couple now has more butter than they know what to do with. The trend has gained traction on social media, where others are copying the hack. This aligns with the current popularity of butter as a snack, with videos showing people eating sticks of butter or feeding it to babies.
The trend fits within the Make America Healthy Again movement, combining animal fats, strenuous exercise, and eccentricity. Some speculate that figures like RFK Jr and Kid Rock might adopt the practice, running with containers of unpasteurised cream strapped to their chests.
While initially baffled, some see potential in combining exercise with food preparation. Ideas include making hand-pulled noodles as a form of battle ropes, kneading dough for an upper-body workout, and stamping fruit for smoothies during cool-down. This culinary CrossFit approach could turn tedious exercise into a productive, if messy, activity.
