During the Ma Strength weightlifting camp 15 year old Shen Guowei (under 62kg) displayed successful implementation of those Saturday frequency when he squatted 200kg...for a double. During our 2015 camp he did 190 for a single weighing at 56kg. Obviously he's in his sensitive period for strength development but a year of squatting heavy twice per week was enough to improve over a year while remaining injury free.
