Order: Scorpiones. These are the largest scorpions found in the United States. Most scorpion stings are not considered life threatening to humans -- the exception is the sting of the bark scorpion, the most venomous in the United States. Most of the scorpions in the U.S. are found in the southwest, preferring the warm, dry climates found in Arizona, California and New Mexico.
In general, walking, whether on a treadmill or a track, works your lower body. This includes the quadriceps and hamstrings in your thighs, the gastrocnemius and soleus in your calves, your hip flexors and your gluteal muscles. Bringing your abdominal muscles into the mix by contracting them helps support your lower back as you walk.
Walking does not have to be done at a fast pace to have stress-relieving benefits. Even a stroll at a comfortable pace promotes relaxation, studies indicate. Meditating while walking had the greatest impact on mood enhancement, according to a 16-week study that involved 135 volunteers divided into five groups.
