The Great Outdoors.
While the weather is totally awesome right now get outside as much as you can. Enjoy the fresh air and get some sunlight. I recommend outdoor workouts and walks as much for your mind as well as your body. 30 minutes of natural sunlight every day gives you your daily dose of Vitamin D. Getting outside is also a great way to break up the monotony of sitting in a office all day. Get out for a walk, do some stretches, breath. You’ll feel, refreshed with more vitality.
Get creative with workouts outdoors too. There are so many things you can do with just your body weight such as burpees, push ups, ab work. Find a park bench and do step ups, dips and lunges. Grab a jump rope, do some sprints. The options are endless. Your mind and body will thank you for it.
