I started doing BBS strength training early last month and it has been going well. However, with two of the exercises I am not seeing so much improvement in one and none at all in the other for two sessions now.

I have two thoughts:- Number 1. Is that although previously seven days between sessions was enough, my body is now taking longer to adapt as I'm 62. Number 2. These two exercises are done last and I'm a bit knackered before I get to them so I am already weakened enough to cause this problem.

Anyone have knowledge/experience of the problem?
