WHEN it comes to training, Zoe Marshall reckons she has the best — and she’s probably right.

The 31-year-old has roped her NRL star husband Benji Marshall, 30, into teaching her how to snorkel.

The couple are holidaying in Vanuatu, where they celebrated three years of marriage yesterday.

And it appears the pair are more in love than ever.

“Super hot snorkelling teacher,” Zoe wrote on Instagram overnight.

“And yes I learnt how to snorkel in a shallow pool... And yes I also wore a life vest in the ocean and yes he held my hand the whole time.

“Not sure how I will go it alone today.”

Zoe and Benji have spent time relaxing by an infinity pool, cruising on a boat and takings dips in waterfalls during their getaway.

“Started the day with my best friends, circuit training by @benji6marshall then mediating, tarot reading and swimming in the ocean @mandijupp My heart is about to burst,” she said.
