Well I've not lost a ton of weight but I've recently started to find that the skin on my arms and belly is starting the sag and hang down. Tbh I'm not too botherd about my belly, but I am about my arms. I've started using light weights on my arms 30 bicept curls and 30 tricept dips a day for the past 2 weeks but no difference yet. Sould I carry on or use heavier weights?
