In November I'll be competing at the IGSF World Championships, veterans class with 2x24kg. This is part of my assistance training at the moment. 7 reps every 2 minutes gives me about 1'20 rest between sets. After I hit 100 reps with 2x28kg in 20 minutes, I'll switch to the 32s. http:kettlebellfitnessdk.wordpress.com20100616edt-for-maximal-strength-development
