I'm 25 years old and 173cm height. I was fat almost all my life until the age of 23 when I decided to lose fat. At that time I was 88 KG. Then in 6 months I lost until I became 72KGs. What I did was just diet with walking for 2 hours. However at that time I wasn't happy with the result of my body because I still saw ugly loose skin. But then my studies started and I got so busy with it. Because of stress I gained fat, so now I'm 77KGs. So I decided to go to the gym now and do one hour of cardio. I do intensive running on the machine for 1 hour (I run at 10K/h for 1.5 minute, and 0.5 minute walking at 5.5/K/h). I burn with this hour 600 calories. Of course I'm controlling my diet now. Not the same difficult diet that I did in the past, but I only reduced my food intake a little and cut sweets and sugar completely. I guess I eat around 2000 calories per day.
When I started training at the gym I was 78KG, now I'm 77KG after 1.5 week.
However I'm really concerned about the excessive/loose skin that I might get since my plan is to loose weight until I become 65 KGs. After that my plan is to start lifting weights to get a toned fit body (I read this question so I'm aware of it, but this is my goal). My biggest concern now is the loose skin. Can you please recommend for me excercises/machines to use to help me tighten my skin?
I need to note that in the gym we have those vibrating machines. A guy told me that these help to tighten the skin, so what do you think?
