Hey Scott yes you are correct 15 secs rest after each rep in the cluster
and 2 minutes between sets, or you can increase the rest by 5 seconds
each rep within the cluster and maintain the 2 minutes rest between
sets, ie; rep 1 – 15 secs rest/rep 2 – 20/rep 3 – 25/rep 4 – 30/rep 5 –
35/rep 6 – 2 minutes repeat times 6, cheers, ash
