When it comes to running shoes. I have tried different styles. Get a good shoe that will last. MY favorite is Hoka Bondi 8. Hoka makes a great running shoe and being a bigger guy, they give support, and they last for many miles. https://amzn.to/3PRDqt7

Good protein is essential to a fitness goal. Helps build your muscles and keeps you feeling full. To hit you protein goal you will have to rely on some type of supplements. There are hundreds out there of all kind of quality. Look for low sugar and few ingredients. A good rule to go by is the grams of protein with a zero on the end should be more than the overall calories per serving. This is my go-to supplement. Easy to dissolve and tastes great. https://amzn.to/3TKyCqO
