Thank you! I hope I can help you on your journey! When I first started losing the weight I just started by walking. My friends and I went to the gym 3-5 times a week and walked on the treadmill and lifted weights. Then I tried the elliptical. And I did that for a long time, until I discovered running. I also did that on the treadmill at first too. But now running outside is WAYYYY better to me than running on the treadmill. But I still will log insane mileage on the ‘mill. I once did a half marathon on the treadmill. I don’t recommend it.
But it all comes down to this: you can’t out-exercise a bad diet. So I radically changed my diet too. I hope this helps! Good luck! And please let me know if I can help you in anyway!
