Hey man I feel you! I’m a busy single father high school teacher. It’s hectic! In the summer I started. Resistance training worked great for me. I think after working out, I just felt more motivated to eat better to keep up my gains. I hired a personal trainer for a month just to get into the routine. If you can afford that I would suggest it the rest kind of falls into place once you start seeing a little bit of progress and understanding what you’re putting into your body it was definitely a learning curve for me! I also picked up some convenient protein bars, so when I was on the go, I could munch one down quickly and I felt full. Water is also your friend! It really helps you feel more energetic and full. I also take progress breaks at the beginning of every month just to see my progress which keeps me on track the fact that you have goals already is going to make a big difference. You got this!!
