Go run around the block and do push ups every time you slow down. Only 10-20. You don't want to slow yourself down. Make sure you finish the whole block. When that is not enough go for two.
You can do this without a gym. ⚡
In-fact I recommend doing this before you start going to the gym.
This way when you go to the gym you will have the energy and stamina to actually work out instead of spending 30mins driving and 30mins doing barely anything.
You got this brother🔥
