I am due to start w4 on Thursday alongside my 11 year old twins who are (slightly begrudgingly) doing the programme with me... I've looked at the weeks to come and am really shocked with the huge leaps from week to week - right now even going from 3 mins to 5 mins running seems like it's going to be almost impossible...
Is there a theory behind the big jumps? I can't believe we can do a 20min run so soon... We will keep at it but it just seems a huge ask. I wondered if anyone can demystify it for me to reassure all of us...
