Don’t worry that you can’t replicate what you were doing before. You can still put together a respectable workout using classic body weight exercises like push-ups, squats, dips, lunges, planks, and mountain climbers. Calisthenics like jumping jacks and burpees will get your heart pumping, too.
This is a great time to buy some basic workout equipment online. A set of resistance bands will set you back $25 or so, and you can snag a set of small dumbbells for $50 to $100, depending on the weights you want. When this crisis is over, you’ll be equipped for those times you can’t make it to the gym.
Think in terms of shifting to a different emphasis or training principle, which many trainers recommend you do periodically anyway. For example, you could go to low weights/high repetitions or focus more on flexibility and range of motion. Take this opportunity to address your areas of weakness, whatever they might be.
