Don't think that is making a fool of yourself - just part of a learning curve...... Perhaps you need another rest day?
Indeed, a fool would have continued.
Yeah fair enough - I just wasn't expecting to have to stop so it was a surprise... Taking it easy this week I think.
Even 5x5 is quite a change from your past interval sessions. Be careful!
Yeah I'll try. My trainings before were all quite short in comparison to this type of intervals!
