- Go to supermarket
- Pick up the largest sack of potatoes/cat litter/bulk dry goods you can find (lift with your legs) or two if one’s not enough for you
- Carry them around a bit while you pretend to look at other items (cardio)
- Change your mind, put them back
- Leave without making any purchase
- Repeat until sufficient fitness achieved


The biggest sack of potatoes in my store is 5lb (2.3kg). But kitty litter… that you do have to lift with your legs.
In the store where I work, we sell a 10kg (~22.1 lb) sack that’s superb for getting my reps in, but yeah, lots of things might work for you! :)
Damn, that’s a lot of potatoes. Keep lifting!
