Utilize what you’ve got. Jog with a log. Body armor and punching bag for squats and sprints. Take the tire and sledge and not only hit it on the ground but tie it in an upright position for a different swing and set of muscles.
Just be the best YOU that you can be. Don’t worry bout everyone else.
Like the eggs are sides for bacon shirt…. honestly not much core stuff done here more dexterity weights are zero other than just plain work…. keep tire it makes a good cover position. Or enough of them and earth’s sship house….a neighbor carbonizes them ( fancy eco way of saying controlled burn) when done with it her waste mater energy is released and refirmed using pressure carbon and heat . End up with activated charcoal diesel fuel, and some metal parts if tires used used burns most grèen farm waste not needed for fertilizer into fertilizer starts and fuels. Trying for a near net zero system of farming. It’s a patented product cycle but I do buy diesel from him for low prices… we trade for bacon and hams
