The Gulag 1 is a training plan designed for minimal equipment. It is either 4 or 6 days per week, depending on if you do the added cardiovascular workouts or not.
It focuses on basic kettlebell and bodyweight movements to get the maximum return from a relatively small time investment. It is a short term program only. It is advised at the end of the four weeks you move onto Gulag 2.
Multiple kettlebells – for men 12-24kg for most exercises with a heavier bell for swings like a 32kg or 40kg. For women 8-16kg with a swing bell of 20-32kg.
