When I do Step, Jump, and Pump (one of my favorites of the Body Blast series), my arms are so tired after triceps extensions and flies (25 lb. barbell and 15 lb. wts., respectively), that I can't really use them to cradle my head during abs. I just start doing the crunches with my arms down by my sides to let them recover. Anyone else's arms too sore after those last weight moves?
