My strategy to conquer Week 2 Day 2 is now following: 90 sec. interval (as required), less repetitions in first sets, but required number of repetitions in last sets (because it's always more difficult to do these last sets). With this "backward movement" strategy I hope to eventually increase number of repetitions in all sets to required 8-7-7-6-10. Next time I will try 6-5-5-5-10 and so on..
