Complete lack of any equipment for a week or two is no excuse to stop working out.
Work bodyweight for a week: push-ups, pull-ups, squats, lunges, burpees, & sprinting.
Even if you’re in the middle of a heavy lifting program, you won’t lose any gains.
You might even gain from the brief respite your body gets.
And, if you really need to find something heavy to lift, pick up an odd object, like a stone, sandbag, or small child.
