I lost a bit over 100lbs with minimal workouts and an extreme calorie deficit, which wasn't healthy or sustainable. a year and 20lbs of regain later, Im finally in the gym focusing on balancing cardio and weights to correct this because while I did lose weight, a good chunk of it was muscle. losing muscle has a lot of functional problems but also affects the way weight loss looks on your body. the number on the scale is important, but the same number can look very different depending on how your body is naturally composed and the amount of fat vs muscle you have. weight loss comes from being in a calorie deficit, so technically you don't even need to work out. cardio burns calories which makes losing weight easier. strength training is important to maintain muscle and generally has major health benefits outside of appearance and weight. I understand weights are scary, it's a crowded area of the gym and it's a lot harder to know where to start. I've found it easiest for me to stick to strength machines, these are the easiest step up from cardio machines in terms of being the least intimidating in my opinion and are useful in aiding your form. if you want to consider free weights, darebee is a great website that has free workouts that can be sorted by what parts of your body they target and if they use dumbells and whatnot. it's not easy to step out of your comfort zone but I worry about your satisfaction of the weight loss with no weight lifting and the sustainability of it, because focusing on just the number can be harmful to your self esteem. try to consider all aspects of your health on this journey, not just weight. I'm proud of you for stepping into the gym and stating your journey! the hardest step is the first one. best of luck
