Most people lift weights with their arms, but what about if you wanted to lift with your feet. Sure, there are machines designed for pumping iron with the lower body but most of these are inaccessible during lockdown. If you want an alternative at home, then consider the monkey lifting weights tool.
This looks a lot like a bulky boot except that there is a mechanism for grabbing dumbbell handles at the bottom. Consider using hex dumbbells with this tool so that there are flat sides on which to rest. Be sure to check the compatibility with handle widths and diameters.
These are pretty sturdy with a load capacity that easily exceeds 100lbs per boot. They are usually sold individually so you need to buy a pair for simultaneous lifting. Watch demonstration videos to learn proper form and safety precautions before use.
