There are ways to customize a workout routine if you’re looking to tone up areas that may be highlighted in your particular style of wedding gown, whether you are aiming to maintain, lose or gain weight.

Kit Rich, a personal trainer and Pilates instructor based in Los Angeles and founder of the Kichgo workout kit, suggests starting at least three months before your wedding date. She notes that the more time you have to prepare, the better the results.

“Set realistic and healthy goals based on the amount of time you have before your wedding day,” she said.

Luke Zocchi, another trainer based in Byron Bay, New South Wales, Australia, and the author of “The A-list Diet & Fitness Plan,” cautions that while you can definitely tone troublesome areas, full body workouts are key to achieving results. “Hit the body parts that you want to tone up a couple of times a week with resistance training and also incorporate cardio sessions into your workout,” Mr. Zocchi said.
