For those of you who have finished the plank challenge I set: 30 days to a 5 min plank I've now done an advanced challenge. Err it is so far just one person and I should finish my final 5 mins in a couple of days!
Just see the "advanced" tab on the spreadsheet and keep updating it.
Spread the word and lets see if we can get more than 2-3 people on the challenge this time. Although anyone can start the 5 min challenge at any time as I've left that on there too.
