Giving it my all... Well kinda

So I wanted to see how far I can go at a high speed. I went at a 8.5 for like 8 mins and tbh I'm so sad with that. I wanted to hold at least a fifteen minute so I'll do this again at a later time. I did the regular arms and core. But increased the weight on each by 10 pounds because my body was getting used to it. Yeah I'm pretty disappointed in myself but at least I have a goal that I need to beat and a challenge  that I have to overcome. My legs still hurt even tho I stretched like everyday but whatever hopefully it gets better
