Take your barre3 practice and nutrition best practices with you wherever you go with the following travel tips:
1. Pack filling snacks.
My go to snack is a combination of brazil nuts, goji berries, raw cacao, and almonds.
2. Stay hydrated.
I always pack a water bottle in my carry-on along with a traveling tea mug to help me stay hydrated. Grab a few handfuls of your favorite tea bags and refill your mug with hot water throughout your plane ride.
3. Pack CALM to help you sleep at night.
This is especially helpful when dealing with a time change.
4. Stretch on the plane.
In your seat, try moving your spine in different directions to help you stay limber. Play around with arching and rounding your back actively. Twists are easy to do while sitting too! If you have a longer flight, you may want to get up and do some crescent lunges and figure 4 stretches in the aisle. We tend to get really stiff and tight when we sit for long periods of time – extra stretching may help your body recover faster after a long flight.
5. Take a walk at the airport during your layover.
Use your layover as an opportunity to stretch your legs and keep your body moving. Bonus points if you do our 10 minute online standing workout in the airport!
6. Bring barre3 online workouts with you!
Deflate your core ball, grab your laptop or iOS device, and get moving! Even if you just have 10 minutes to exercise, do it. Your body will thank you. Read about the benefits of 10 minutes here.

There was a great post on the Lululemon blog about things to do pre- and post-boarding and stretches to do on the plane to keep blood circulating and help prevent bloat. I still use it every time I fly!
