I’ve just recently graduated and consolidating, however recently I’ve signed up to do Joe Wicks 90 Day Plan (I’m pretty big on fitness in the last few months - along with strength training I lost quite a bit of weight, however haven’t really gained a lot of muscle that’s showing apart from my calves) ...which is only HIIT (High Intensity Interval Training) exercises.
The FAQ says that I can do 2 runs in place of 2 HIITs (I’ve yet to receive my plan so can’t really tell how often my workouts would be but would guess 4 or 5 a week?) and they recommend in their FAQ that the distance they recommend for these two runs is 5K. I do an average of 10K a week now, but I only do an average of 3.5K because I do 3 runs in the week as the programme stated. Will my fitness go down if I build up to 5K and then only do 2 5K runs a week, or shall I contact the programme and see what they can do and keep to my three?
