Congratulations!  You have reached the final 2 weeks of your 8 week program.  You should now, whilst possibly a little tired, be feeling much fitter and more invigorated.  Consistent exercise gives you an enormous sense of satisfaction. Weeks 7 and 8 also require you to train 5 days/week.  If you did not manage that in weeks 5 and 6 you should definitely aim to do it now.   You can select any 5 days but it is better to spread it out as much as possible.  On 1 of the other 2 days you are encouraged to walk continuously for 30 minutes at an uncomfortable pace.  The 7th day you can have a rest.   You will need a stop watch for some of the sessions.  You could even download a free timing device from the app store (for example, Interval Timer)
