@florbelle... I don't think its about choosing the least weight, or choosing the weight that matches any of your particular prior sets. Its about hitting your HIGH POINT. Which is supposed to come during this x12 + x12 Superset. You choose the heaviest weight that you can complete the first x12 with and complete or NEARLY complete the second x12 with.
Aaaaah! Thank you all for your postings. You have cleared up the High Point dilemma i was having.
I am in week 6 and have been really struggling to complete upper body workouts in 46 mins. I am doing it correctly just can't seem to finish in less than 52 mins. Often it takes me an hour.
Yet I can always do my lower body in the alloted time which is weird because with l/b, the machines are placed all over the gym!
I sometimes don't leave a full minute between the sets and as I am getting stronger and when
finding some weights are just too light after a rep, I have been going up a weight and doing the same amount of reps so that I 'feel' like it's working.
e.g.
Dumbell Flyes (new exercise for me on Monday)
12 - 3kg
10 - 4kg
8- 5kg
8 - 7.5kg
6 - 8kg
12 - 5kg
12 - 15kg
OR
Side raises (tough for me!)
12 - 4kg
10 - 5 (did 6) + 4kg (4)
8 - 5kg
6 - 5kg
Clearly need to come down to start off the side raises - but is this ok? IF I can't manage to finish a full rep set, to drop down and complete the number of reps?
