Exercise Challenge of the day!

Iv been having a real hoot with this, it all began 3 weeks ago when a couple of PT clients suggested we did and 'Exercise of the day'  challenge - high reps to make it tough, we were then to check in on Facebook or Twitter once we had completed the challenge - kind of Team Motivational support adding in that extra Boom!! to our training regeme.
So we began posting our daily completed challenges, then other friends/followers started asking 'Whats this Challenge thing you are running Nicki?  can I join in?'  
Only three weeks in and we have a group of over 63 challengers joining in each that I am aware of - there could be more because I know family members are also taking part now too.  I have people in Amsterdam, USA and even Australia following - The exercise virus is spreading AND whats even better is that people now feel 'Guilty' if they haven't checked to see what we are doing for the day.
So we start at day 1 =100repetitions of the given exercise, day 2 =110 reps of a different exercise, day 3 = 120 and so on for 5 days.  You do not have to do all the reps in one go, pit stops are allowed as for some it is quite a challenge.  So long as you get all the reps in during the day you have ACHEIVED!!
If you want to play 'catch up' the here are the exercises we have done so far, if you are unclear of what to do either follow me on twitter/Facebook and look back through the posts and see the pictures or google them:-
