So, I found a group on Facebook entitled "30 day fitness challenges"
I'm probably jumping in the deep end by taking up 3! Sit ups, Squats and push ups.
I've just done my first set, and I'm not going to lie, I struggled! Push ups were a disaster and that only starts with 3 on the first day!
Sit ups start with 20 and works up to 140. I started feeling it by 5 and struggled by 10!
Push ups start with 3 and works up to 20. I could barely do 1. This is the easy version of the challenge, there is a "normal" one that starts with 15.
And the Squats start with 50, building up to 250. I had to rest for a second or two after each set of 10. There is also a harder version of this that Starts with 250!
There a lots of others so probably something for everyone.
