You must use at least 10 gallons pots for your plants. Then you can curl these pots, but do it right after a good watering to assure they are adequately heavy enough. Do 3 sets of 10-12 reps.
You can also run a mile with one of the pots strapped to your back. Be sure you are in a medical state or you might get reported with an MJ plant strapped to your back.
