Op you’re absolutely right this is exercise, however your low bmi info was missing from your op and was a critical point. So all posters who didn’t know that are right. They thought you were over weight as you said you were fat. You now need to exercise, yes. Mainly strength training.
when I lost weight and hit goal, I looked like I lost weight, and I had lose skin, a year of body composition and eating my protein, even though I did it throughout. Has made an enormous difference.
you need to tone up and build muscle. There is no other way round it. I’m sorry. I’m fit and toned. I have muscle definition. Which is very visible. When I first lost the weight my husband and daughter said I looked too thin. My daughter said to me at the weekend I looked a normal healthy weight now. And I was in my underwear. My weight was the same at both points.
you need to start small and build up. As you do it it gets easier fast.
so for me. Every morning when I get up I do these exercises. It takes about 15 mins.
i do planks, squats, hip flexors, sit ups etc. all using my body weight to strengthen.
then when I get time I go for a run, a fast run now,on the treadmill. just 20 mins. That’s made the biggest difference to my waist. I then either do full upper body weights, which takes another twenty mins, or I do something like rowing, bike or incline climber.
so all in most days I do 45 mins to an hours exercise. And it shows. I also take creatine to help build muscle and recovery.
when I started I couldn’t do a tenth of that. But it jisy becomes easier and you realise you can do more. You also need to eat a min of 1g of protein per kg of body weight, but to build muscle aim for a min of 1.5.
it takes time and energy, but I promise it gets easier, and you do get the results.
