Shake off calories and tone your booty with celebrity trainer JJ Dancer!  This cardio dance boot camp is such a fun way to work out that you're sure to do it over and over again.  Be prepared to get the heart rate up, sweat it out, and shake it for a solid 20 minutes.

Whether you're going away for a 10K, your first marathon, or a triathlon, packing can be overwhelming and stressful, but Clif Bar's dietitian Marni Sumbal MS, RD, CSSD, LD/N — 11-time Ironman finisher, Ironman coach, and total expert on how to pack for an out-of-town race or event — has some solid tips for you.  And by tips, we mean how to avoid total rookie mistakes that many of us have made in our early racing days (and might still make on occasion).

There's a fine line between packing enough and packing too much — Marni helps us figure out how to toe that line and pack for success.  Traveling for a race is fun and exciting, so make sure packing woes don't put a damper on your experience.

1. Mistake 1:  Not Bringing Your Special Foods.  "Not bringing along must-have food items is a huge mistake," said Marni.  Relying on stores when you get there and "hoping to find [your special foods] locally, like a specific kind of nut butter, bread, cereal, etc.," is a risk you don't want to take for a big endurance event.  Pack that stuff!
    
2. Mistake 2:  Not Making a List.  The next big mistake?  "Forgetting items!" said Marni.  "Make a list so you don't forget, especially if you are rushed when packing."  A good rule of thumb?  Don't leave your packing to the last minute.
    
3. Mistake 3:  Not Bringing Extras.  Marni says to always have backups of your go-to products, just in case.  "Two pairs of run shoes, extra goggles, nutrition, etc."
    
4. Mistake 4:  Not Checking the Weather.  Marni reminded us to always "check the weather ahead of time," saying that "even if weather says hot or cold, assume that the weather can change.  Always bring extra gear for the 'just in case.'"  So have your ideal race-day outfit and then a backup for another temperature (i.e., if your go-to is a tank and shorts, bring a long-sleeved tee and leggings).
    
5. Mistake 5:  Overpacking and Overwhelming Yourself.  The last mistake was "bringing too much and feeling overwhelmed," she said.  "Packing is stressful.  Keep a list of items you use in training so that you don't overthink what you need for race day."  Plus, no one wants to pay those oversized bag fees on an airplane, right?  Pack extras of the basics and must haves, and ditch the rest.

Looking for a full-body fitness upgrade?  We highlight a simple boxing workout you can do anywhere.

Aside from being a full-body activity that works every single muscle, boxing is adored by many because it can be practiced anywhere.  Obviously you can't take bags and gloves with you as you hit the road for your holiday travels, but you can certainly perform a boxing-inspired workout that requires little to no accessories.  So whether you are looking for something high-intensity you can do in your living room or want a reliable fitness routine to do on your upcoming vacation, we reached out to two powerhouses:  Reebok, a fitness brand that's been leading the charge in creating product specifically for those who want to train like fighters, and Dara Hart, at New York City boxing gym DOGPOUND.  The result?  A kickass workout that focuses on cardio and footwork.  With the rise of combat-type sports and fashionable gear that's specifically made for these types of disciplines, it's the best time to give this a shot.  Check it out ahead.

1. Begin with a 10-minute jump rope warmup

Boxing is centered on hand-foot coordination, and a jump rope is the perfect way to practice these skills.  Plus it's lightweight, making it an ideal travel accessory.  Throw on your combat-approved hoodie that will help you train like a fighter, then get ready to work.  At DOGPOUND, where Hart teaches, they always begin workouts with jump rope.  "Jump rope is the perfect way to warm up, get the blood flowing, and prepare your body and mind for a workout," Hart says.  "At DOGPOUND, we begin every boxing session and boxing class with a 10- to 12-minute jump rope."

Proper Technique

Hart says you always want to make sure the rope is the correct length for your height.  "Stand on the center of the rope and pull the handles to exactly the height of your armpits.  If it's too long, a simple knot or two (or three for me!) tied by the handles can fix this," Hart says.

The Exercise

10-minute jump with added time to stretch.

• 3-minute warmup (basic jump) into a neck and shoulder stretch
• 3 minutes of variations (1 minute per variation:  shuffle, jack outs, high knees) into an arm/torso stretch
• 3 minutes of variations (crisscross, kick outs, double unders) into hip/leg/ankle stretch
• 1-minute freestyle

2. Squats with the jump rope

Next up, you'll transition to squats, adding in an overhead motion that really kicks things up.  Hart explains this move in full:  "A lot of the movement we practice in our boxing program focuses on elongating the reach of the arms.  Boxing is all about creating a 'long reach';  if you can lengthen your arms to the max, you will be able to have more accurate punches."

The Exercise

Stand with legs hip-distance apart and squat down as though you were sitting in a chair.  This is different from an ordinary squat, because your arms will be involved.  Hold the jump rope out in front of you as you squat down, keeping the ends of the rope tight.  Be sure to keep your knees behind your toes throughout the move and to keep your shoulders relaxed.  By squatting with arms above the heart center, you are automatically elevating your heart rate.

• 3 sets of 10-12 squats, keeping your core tight and arms out straight in front of you

3. Boxer-style push-ups

Next you'll hit the floor and transition to boxer-style push-ups.  Rather than placing your palms flat on the ground, your hands will be in a fist.  "You don't need wraps to perform these push-ups, but they do offer support for the wrist and hands if needed," Hart says of this move.

Proper Technique

To get into the proper position, you want a tight fist, with elbows slightly behind the shoulders, and chest to the floor.  If modifying, elbows must at least come to 90 degrees.

The Exercise

• Novice:  4 rounds of 25
• Intermediate:  8 rounds of 25
• Advanced:  12 rounds of 25

4. Jab-cross jackknife

No fitness series is complete without ab work.  This move is more dynamic than the traditional sit-up, but it's a great one to add into a boxing workout.  "This ignites your abs, and adding an alternating left and right punch per rep elongates your reach and works your obliques," Hart adds.

Proper Technique

This move is all about the twist.  Start on the floor with legs hip-distance apart.  "I like to do these with one foot on the floor, for support as you fold your other leg and torso upwards, throwing a left jab and right cross towards the lifted foot," Hart says.

The Exercise

• Novice:  4 rounds of 20
• Intermediate:  8 rounds of 20
• Advanced:  12 rounds of 20

5. Throw some jabs

Everyone knows the jab — it's the flashy, contact part of boxing — but there's an art behind it.  "The jab is the measuring stick to you and your opponent and sets up following punches and other offensive and defensive movement," Hart shares.  You'll want to get the form right.

Proper Technique

Understanding the fighting stance is essential to the jab.  You'll want to start with your left leg in front if you're right handed, and keep a light bounce in your legs.  Keep your abs tight.  Hart explains how you can land the proper jab:

• Step 1 (from fighting stance):  Bring left shoulder to chin.  This protects your face.  It also works the muscles in your upper back and traps.
• Step 2:  Extend your arm.  This should be done at least to the level of your face.  Your fist must be tight, engaging the muscles in your arm and forearm.
• Step 3:  Turn over your fist and reach.  The power is at the end of the punch;  turning the knuckle over assists with this and also protects your hand and shoulder.  The reach engages the abs, glutes, and legs.
• Make sure to keep both feet firmly planted.

Once you complete step three, the hand immediately snaps back to the body, protecting the face and arm protecting the rib cage.

The Exercise

• Novice:  4 rounds of 10
• Intermediate:  8 rounds of 10
• Advanced:  12 rounds of 10

Lea Michele is no stranger to hiding her passion for working out ... more specifically, tapping it back at SoulCycle.  The singer, actress, and devoted indoor cyclist never completes a Soul session without a sweaty selfie.  So when we chatted with her during the Shape Magazine Body Shop event, we were surprised to learn that if she could choose one workout for the rest of her life, it wouldn't be SoulCycle.

Instead the singer explained that her go-to workout of choice would be CorePower Yoga.  "I love SoulCycle, I really do, but hot yoga is something I've been doing since I lived in NYC.  Johnathan Groff and I used to do Bikram yoga before, after, and in between shows.  There's just something about yoga that is so great for mind, body, and soul and I just think it's so fulfilling.  I love the heat and sweat you experience when you're in the room."

In addition to the mental benefits of hot yoga, Lea shared that she enjoys the physical benefits, too.  "There's no workout that makes my skin look better, helps me detox better, and lose weight quicker.  There are just so many perks from that particular practice so if I had to pick one for the rest of my life, hot yoga would definitely be it."

If you've never used a wall to do yoga, this is a perfect calming, beginner-friendly sequence.  Do this 11-pose sequence to help you wake up in the morning, to wind down in the evening, after an intense workout (these are great stretches for your hips, lower back, and hamstrings), or if you're new to yoga or recovering from an injury.

Legs up the Wall

• Sit down as close as you can to the wall.  Lie down on your back, place your feet on the wall with your knees bent, and scoot your butt against the wall.
• Extend your feet straight up, resting your heels on the wall.  Keep your arms by your sides or by your head (this position will stretch your shoulders).
• Close you eyes and allow your entire body to relax, feeling gravity pulling you down as the wall supports you, holding for five or more breaths.

1 Leg up the Wall

• From Legs up the Wall, lower your left leg down to the floor.
• Breathe deeply for five breaths.
• Slide your left leg back up and then repeat this stretch on the right side.

Butterfly

• Extend your arms out wide in t-position and gaze to the right.
• After five or more deep breaths, lift your knees to the chest and roll them over to the right side, gazing to the left for another five or so breaths.

Deeper Spinal Twist

• Come back into the Spinal Twist on the left side.
• Extend your left leg straight so it's resting against the wall.  Allow your right knee to fall in front of it, feeling an even deeper spinal twist.

Shoulderstand Prep

• Come into Legs up the Wall.
• Press your feet into the wall, lifting your hips off the floor.
• If you can, the knees and hips will hover above the shoulders.
