Absolutely. The right treadmill will serve you well for years to come, but if you only want one for what will hopefully be a few months of isolation, hiring one is an option that's worth considering. You can hire a great quality treadmill for under $30/£20 a week.
Treadmill hire companies all offer a range of different models, so the same considerations apply in terms of size, space, speed, and accessibility of controls. Demand is high right now, but hiring a treadmill isn't an option everyone is likely to consider, so it's well worth investigating.
Due to the logistics of delivering and collecting treadmills, the best way to find a hire company in the US is to search for one in your city or state. Some good options for the UK include Momentum Fitness Hire, Hire Fitness and Homegym.
