Summer is a time to take long vacations and evaluate your life goals, right? Not for these entrepreneurs. These are pushing hard to build a company, and their day always starts with a morning workout. It's amazing how a brisk walk or a few laps in the pool can energize you and give you the push you need to tackle tough problems.

1. Wake up by swimming

"My morning exercise is typically conducted in the pool, as swimming makes me a better me. It wakes me up, allows me time to think, and aids in my focus on the important issues for the day ahead. Additionally, swimming makes me feel more relaxed and happy so I am ready for the day ahead." Kevin Day, founder and principal of Day & Associates

2. Do a high-intensity workout

"My wife and I are both entrepreneurs, so our schedules are often unpredictable and hectic. We do Barry's Bootcamp together at the same time every morning in order to have a routine and spend time together. The workouts are an hour long and include high-intensity interval training and strength training focusing on different muscle groups each day. I've tried a lot of different workouts and fell in love with Barry's, because the mental and physical challenge it presents is similar to starting a company. You need both endurance to build something that will last and the ability to push yourself to the brink. It's the hardest workout we've ever done, but that sense of accomplishment first thing in the morning sets the tone for the rest of the workday." Chase Garbarino, CEO of VentureApp and former CEO of Streetwise Media

3. Meditate and walk the hills of San Francisco

"My morning exercise routine balances mental and physical activity. I begin by preparing my mind for the day by meditating for 30 minutes to center myself, then I walk 2.5 miles through the hills of San Francisco to the office where my first two meetings are usually held walking around the Palace of Fine Arts." Redg Snodgrass, CEO of Wearable World

4. Change up your routine

"I am a workoutaholic! For me, the best medicine is a good one and a half hour workout before heading off to work. My workout routine varies from day to day and includes free weights, full-body elliptical, brisk treadmill walks, and my ultimate head-clearing activity, jump-roping with weighted handles. Another area of keen interest for me is photography. I spend countless (and I do mean countless) hours taking and editing photos. One of my favorite times to edit images is in the early morning before work. It tends to put my mind in the right place before I head out to take on the world at work!" Al Green, CEO of Kent Displays

5. Hit the bike (or the stairs)

"In Newport Beach, California, where I live January through May, I combine trainer sessions with classes at Grit Cycle, which is a cycling class that works the lower body, but also works the upper body with weights at the same time. It is brutal. Grit Cycle was founded by John Wayne's granddaughter, thus taking the name from his famous movie True Grit. It is true California style, with space (and water bowls) for dogs to hang out while their owners are taking class and eucalyptus towels at the end of the class, which are definitely needed. When not at Grit Cycle, there is a very long set of stairs in Corona Del Mar overlooking the ocean and the Balboa Peninsula where fitness enthusiasts, in general, do repetitive sets of stairs and lunges for their exercise. Here is where I train three days a week with a great young trainer, herself a survivor of breast cancer. Our work here is a combination of running up the stairs, lunging up and down the stairs, and working with resistance bands. You can't beat the view." Chris Goddard, president of CGPR

6. Vary what you do each day

"My prework workout routine begins on Monday with a spin class, a run with my buddies on Tuesdays and Thursdays, and I hit up bootcamp on Wednesdays and Fridays. I like to mix up the activities and people I work out with to keep the workouts feeling fresh, while being able to keep up with friends since my days are busy and my evenings and weekends are reserved for family. After completing my morning workout, I'm able to come into the office feeling energized and ready to take on the day." Jen Colton, principal of Flashpoint PR

7. Get full bars on your activity tracker

"As a working mom and running Polar's marketing globally, my morning workout plays a very important role in getting me set up for the day. Whether it's a half-hour jog before the sun rises, 15 minutes of meditation, or cycling to the office, I get a boost of energy that helps me to stay focused. I get such a sense of accomplishment when I see that my daily activity bar is full on my Polar watch by 8 o'clock in the morning. I know it's gonna be a good day!" Lei Sorvisto, group marketing director of global at Polar

8. Ride your bike to work

"I love getting a workout in before going to the office. Gets the body and mind pumping, and the mornings are usually free from distractions. On most mornings, I either go do a CrossFit workout or get on my bike. I often ride my bike to work." Jason Fass, CEO of Zepp
