Most of these exercise have shown the typical
format that we suggest you can do. For some an added Level 2
and sometimes Level 3 are given, which are a little harder. These should only be tried
once you are competent at the previous level and want more of a challenge.
Always reduce the number of repetitions when you make an exercise harder until you
are confident with it.
