Aiming to Become a Healthy Pig, Not for Dieting

After giving birth, I've gained 8kg (which has been settled for 3 years now) and I'm about to hit a new digit. Along with that, I'm experiencing headaches every period, leg swelling, stiff neck, and a damaged back... 😢 Making weight loss the goal leads to stress, and that stress gets passed on to the kids, so I'm going to exercise with the aim of becoming a healthy pig. I plan to use the apartment community gym. There's no PT, of course, and I'll be eating the same as usual!!! I'm usually a lazy person who does zero exercise and just lies around, so I figure just maintaining my current diet and exercising will drop 3kg. Slowly, gradually, it's okay even if it's not noticeable~ Let's just be consistent enough not to wreck my body. *In case I don't know how to use the equipment! I joined to ask questions! I'm off to hit the treadmill now!
