What's Up Memostotle,
I currently train myself and others in my basement and backyard. Great way to workout in the sun, never wait for equipment, and keep things interesting. Right now, I have the following:
- Kettlebells (1x8kg, 2x16kg, 1x24kg)
- Farmers Handles
- A Keg Shell
- Dumbells of various sizes
- Barbells with bumpers and iron
On my list of equipment to buy/acquire/build:
- Tractor tires (about 400lbs. Can be gotten from local farms for free if you're lucky)
- Atlas Stones
- Boxes for box jumps
- Logs for clean and carries
My favorite thing to do right now is do circuits where I hit something heavy then immediately go to something more metabolic then rest. So I'll bring the barbell out and do something like 3 heavy power cleans, followed by an overhead keg carry across my backyard and then immediately do 15-20 swings with the 24kg kettlebell. Then rest for 90seconds and repeat with a little bit heavier weight on the clean. Do that for 7 or 8 sets. Combining barbells, sandbags, farmer's handles, kettlebells, dumbells, bodyweight movement, and sprinting, you can probably do a different workout every day for 10 years and never get bored.
For sandbags, I've heard Iron Woody is really good and might get a few of my own
For kettlebells, check if you have a play it again sports nearby. You can get Apollo KB's for 1.60 a pound, which is an awesome price for new kb's. They're not as good as Dragon Door or Ader but they do the job.
Good luck with it!
