Traveling and staying in shape can be tricky, but with Memorial Day Weekend behind us, it’s officially the start of summer, meaning that if you can sneak out early on a Friday to get in a few extra hours at the beach, or on the mountain, you should. Sometimes a hotel gym is just sad, leaving you with few options for getting a workout in. We called in the experts to hear how they motivate themselves while traveling and to see what exactly they pack in their carry-ons.

The Experts

Who better to turn to than trainers who travel frequently? We chatted with four certified trainers about what their top picks are when traveling — how do they stay in shape without adding bulk to their carry-ons? Joe Holder, is a Nike Master Trainer who works with athletes like Nastia Liukin and the NFL; Krystal Salvent is a NASM-certified personal trainer, run coach and cycling instructor who just finished up a 100-mile race in Tahoe, Chris Heuisler, who runs Westin Hotel’s Global Run Concierge and Gerren Liles, CEO of Vision Fitness and Equinox master instructor.

Chris Heuisler

Heuisler is in charge of leading over 250 Run Concierge’s in Westin Hotels, which means he’s on the road a lot. “My job is to help guests stay fit and active on the road, so I know how important it is to keep up your routine while traveling,” Heuisler says. Westin has made huge leaps to make its hotels the most travel and exercise-friendly, resulting in partnerships with TRX, Peloton and New Balance. “As I travel frequently from property to property to train run concierges and run races, these are the things I make sure to always have handy to help me stay fit on the road.”

The Roll Recovery R8

“This deep tissue massage roller is a must-have for athletes everywhere. Yes, it has wheels from roller blades, but they’re incredibly effective and it is key for recovery. It’s compact enough to take everywhere.”

Resistance Band

“A key part of any training routine — it’s easily stored and perfect for a quick hotel workout on-the-go. I have a quick two-minute routine which opens up my hips and warms up the glutes.”

“This is one of my favorite parts of my runWESTIN garb and something I absolutely never travel without. It includes a small compartment to carry my hotel room key, which is perfect when I am running or at the gym.”

Garmin Forerunner 235

“This has been my go-to watch for three years now. And while I do often enjoy just running in a new city for the fun of it, I’m also keen on tracking my mileage as I do so.”

SOS Hydration

“Dehydration is a major issue when traveling. I always have a few SOS Hydration powder sticks in my carry-on to make sure I’m ready to hit the ground running wherever my travels may take me.”

Joe Holder

Holder just got back from leading a retreat at the W Hotels in Mexico, where he, along with three other trainers lead a group of travelers through a Detox Retox Retreat. But when he’s not doing that, Holder can be found jet-setting (for work, naturally) between New York and LA lending his expertise to everyone from fashion models to NFL players to top chefs to the everyman.

Holder is a zero excuses kind of guy, especially when traveling. “Working out is typically the easiest thing to do when you travel. Honestly, you just have to make time for it. People make it more complicated than it needs to be,” Holder says. “Just research the area before you travel, find some studios and if that isn’t the case, you have your body, feet, or some simple equipment or app to keep you moving. Your hotel will [likely] have a gym, as well, even if it’s small.” Beyond just fitness tools, Holder also travels with a variety of tinctures and proper nutrition. While it sounds like a lot, he has it down to a science.

Lacrosse Ball

“I travel with a lacrosse ball or some massage ball to keep my feet loose, but at the same time you can just use a foam roller in a similar way.”

Nike+ Training Club App

“Equipment is a bit overrated when it comes to travel. I just have running shoes, Nike+ Training Club App and a jump rope.”

Hypervolt

Recovery is super important — especially when traveling. “I always bring a TheraGun or HyperVolt and often times a PowerDot.”

Robyn

“Sleep is the ultimate recovery [tool], and we often forget about that, so I try to find things that will calm me down. I always have a bunch of tinctures, but I’m loving Robyn, which is a CBD mix via mineral health for relaxing at the end of the day.”

Ginger Tea

New foods and a change in schedule can wreak havoc on your insides. “A plant-based protein and/or ginger tea to make sure my digestion stays on top of itself when I’m on the road.”

Gerren Liles

The Equinox master trainer and CEO of Vision Fitness travels often for work, and for pleasure, so he’s learned exactly what to pack to keep up with his routine.

Revere

Liles packs both the pre- and post-workout mixes. “These awesome all-natural supplements fuel and re-fuel me when I work out.”

CrossCore Suspension Trainer

“It’s basically a TRX on crack. The straps are on a pulley, which demands greater core engagement to maintain stability through various movements.”

Jump Rope

“Easy to carry, top-notch cardio and conditioning tool.”

Hyperwear Sandbell

“A compact tool that I can create multi-dimensional movement with load. It challenges my grip strength and allows for dynamic movement like slams and throws.”

Krystal Salvent

The certified trainer and cycling instructor is definitely active when she travels, choosing to run Ragnar Relays and cycle 100-miles while she’s away from home. Same as Holder, she packs resistance bands and a lacrosse ball — “I use them for many different things. I like to start my workouts with dynamic exercises which help warm me up. Before running, squatting and push movements (i.e. push-ups) I do lateral band walks, banded squats, lateral side steps and clam shells.” Salvent also acknowledges that traveling with a foam roller can be tricky, which is why she grabs lacrosse balls for her glutes, calves and lats before using resistance bands.

REI Force of Nature Nalgene Water Bottle

“Nothing like staying hydrated before, during and after a flight. There’s no waste, it’s good for the planet and I can stay aware of my hydration level.” While this specific one is no longer available, you can never go wrong with a Nalgene.

Skratch Lab Hydration Mix

“This is everything. The only hydration powder that doesn’t make me feel ill, shakey, itchy and gives me a little kick while doing my workout. No need for pre-workouts, and mixes easily alone or with the collagen protein.”

Vital Protein Collagen Peptides

“Great source of clean protein that mixes well in just about anything.”
