Don’t worry about what everyone else is wearing around you – this isn’t a fashion show. For shoes, look for a minimalist shoe with a hard, non-compressible sole. Chuck Taylors are my personal favorite, but Steve wears Vibrams or Merrills. While there are some great shoe options specifically for weight lifting, as a beginner, the above multipurpose shoe will serve you just fine!
After session 12, consider whether you need to increase the weight for any particular exercise. If you can comfortably do more than the RM of 12 exercises, increase the weight by a modest amount, say two pounds or a kilogram for isolation exercise muscles such as triceps and biceps, and 5 pounds or 2.5.kilograms for compound and large muscle group exercises like squats and deadlifts. When using dumbbells, this would apply to each one. Don’t increase the number of sets beyond 3 at this time.
