The festive period is staring you down. Calorie-laden and drenched in gravy, your waistline should be worrying at the thought of marathon meals, boozy Christmas parties and more snacking than you can shake a andy cane at. But worry not, gents. Behind the latest door of the annual Gentleman’s Journal advent calendar is your seasonal salvation.

Gym Marine, the specialists in home and marine fitness, have partnered with Gentleman’s Journal to offer one lucky winner the chance to win some top-end equipment. Namely, a pair of Stairmaster TwistLock Adjustable Dumbbells. With the ability to change weights in 5 lb increments with the simple twist of a handle, these are a great way to get results from a smart, compact design.

And it pays to follow the example of Gym Marine. When we spoke to Edward Thomas, Director at Gym Marine Yachts & Interiors earlier this year, he told us that the brand “offers gym layout planning assistance and consultative advice on the creation of your gym space at no cost — and supply equipment at competitive prices.” Enter below for your chance to win.
