I recommend the following equipment:

• A competition rack and power bar (I prefer the Elitefts combo rack and Iron Cowboy bar)
• A belt squat machine (the Westside ATP is the gold standard here, but any belt squat will do)
• A sled to push and pull (the Prowler is great, but Spud sells a very cheap alternative)
• A dip and chin station (anything will do)
• Access to a commercial gym with dumbbells, a Smith machine, seated hamstring curl, pec deck and cable station
• The Mountain Dog band pack

You can get by with this:

• A power rack and power bar
• A sled to push and pull
• The Mountain Dog band pack

The course lessons contain some suggestions for exercise substitutions if you need them.
