I am a huge proponent of mixing things ups
There are many schools of thoughts on which one burns the most calories. Some say when you do cardio first, you burn your quick energy stores, putting you into “fat burning” mode during your strength section.
I prefer cardio first, this ensures that my muscles are ready for strength work.
I also like splitting it up in 10 minute sections/cardio/weights/ etc
Keep you body guessing!
