I am 40 with 4 young kids under 9 and a husband with a very busy work life who travels a lot. I work part time and every moment I’m not with my kids, I’m trying to get my work hours done or doing housework. Used to run lots in my 20s and have generally stayed active always but recently I’ve put on a bit of weight and now my only exercise is a 10 min YouTube video at 9pm when I can be bothered. New Year’s resolution … lose the 6kg I’ve put on in the last 5 years and get fitter! Thinking of renting a cardio machine as a trial as realistically I can’t get to a gym or leave the house for a run all that regularly. Shall I get a cross trainer, treadmill or row machine? Any tips on quick HIIT videos I could be doing? Tempted by a treadmill but worried about my knees now 😬
