Hi – started on monday and doing mon/thursday as fast and sticking as closely as possible to what the NHS site thinks should be the calorie intake for my current weight. Also doing around 13k steps a day and started the 7min workout which I did yesterday for the first time at about half intensity. Still have muscle aches. First time doing anything apart from doing the first month of P90X a couple of years ago which lead to injury and crashing off the wagon.
