PARK SLOPE, NY — Love-sick gym rats can profess their love the same place they pump iron this year — on Valentine’s Day, no less.

Blink Fitness will marry five lucky, buff couples at the Blink gym on Fourth Avenue this Feb. 14 holiday.

One-hour time slots between 10 a.m. and 4 p.m. will go to the first five couples to register online before Feb. 11 — and Blink will pitch in with $1,000 to the first three registered couples in the form of a Visa gift card, a representative of the gym said.

For all five couples, Blink will provide flowers, food and drinks, a photographer, invitations, a Blink swag bag and an ordained officiant.

Blink Fitness has always been a place for lovers — and it’s already at the core of some New Yorkers’ love story.

Last year, the gym sold fitness bouquets complete with a blender bottle, jump rope, lifting gloves and protein bars for swooning fitness lovers ahead of Valentine’s Day.
