Lucy Activewear® was founded in 1999 in Portland, Oregon by a group of like-minded women who felt that workout wear should not only support your athletic pursuits, but should be stylish and flattering, too.

All of their clothing is designed and developed by active women for active women. So whether it’s yoga, pilates, running, outdoor exploring or traveling that ignites your passion for life, Lucy has the clothing to let you shine from the inside out.

Take advantage of the warmer weather by taking your running sessions outdoors. Start off with the perfect pair of running shoes like the ever-popular ASICS. Taking the time to pick the correct type of running shoes for your pronation type is key to avoiding injuries on those long runs on concrete and asphalt.

When running outside in heat and humidity, it’s essential that you pick lightweight clothing with moisture-wicking properties. For women, try the sleek Fizz Tank II from Sugoi and the Adidas Stella McCartney Running Performance Short. For men, pick a comfy muscle tank, like the Adidas Response Tee, to keep cool on your run. A pair of lightweight shorts like the Nike Four-Inch Woven Short is a good basic.

Running outside also calls for some extra safety precautions. Here are 5 tips to make your runs safer and more comfortable:

1. When listening to music, keep the volume low enough so you are able to hear cars and cyclists. Never assume that a car can see you.

2. Run facing the traffic.

3. Be careful not to run on paths where you are consistently on a slant. This is very hard on your hips and knees.

4. When running in low light conditions, wear reflective materials.

5. Wear sunscreen when running in the daytime. SPF 30 or above is best.
