IsoMax 6x6: Week 3 1-Rep Max Retest

One of the underlying concepts of the 6x6 program is training with a target load of 70% of 1-rep max force. Setting the IsoMax to this target load ensures the trainee is applying at least 70% 1RM force to get the bar to start beeping. The trainee is advised to retest 1-rep maxes for the chosen exercises every 2-4 weeks. So, based on recent performances in the Zercher Squat and Drag Curl in excess of the originally tested 1-rep maxes, I decided to retest today. These are the new 1-rep maxes, with new target loads generally rounded up to the nearest whole number from the calculated 70% values:

• Zercher Squat - 140.67, up from 101.4. The 40lb jump is a reflection increased comfort and confidence in the position. New target load = 99.
• Overhead Press - 85.27, up from 83.9. Modest gain but I'll take it. New target load = 60.
• Drag Curl - 153.4 up from 124.67. My force output in this exercise is as high as it is because I use the back-to-hands spiraling technique taught in this video. This technique recruits just about all the upper back muscles as well as the lats and abs. The My CNS seems to find more muscle groups to recruit on my highest performing days.
