Gyms are where many good intentions get ground into hand chalk, but worse than that, some would-be exercisers leave frustrated or injured.

Currently, Centers for Disease Control and Prevention exercise guidelines call for all individuals to do 150 to 300 minutes of moderate-intensity exercise per week, or 75 minutes of high-intensity exercise per week. In addition, the CDC recommends two days of strength training, or muscle strengthening, for obese people.
