Hey I'm trying to get the weight off I gained over covid when I had 4 months out of work. I'm doing 2 hiit days and 2 strength days out of 7. Is this enough because I'm finding the weight is really slow to shift. I'm 37 and have never found it this hard and wondering if age is a real factor? Supposedly it is a factor after talking to my mates so just wanna get some insight.
