It depends on where you’re at with fitness and health in general. Prioritize being well regardless of feedback here. That includes adequate rest, nutrition, hydration, etc.

For most folks, consistency is by far the most important factor. Stick to a schedule that works for you and do what you can. Maybe set up something like this:

• “the goal”: what you’d like to be able to do

• “the bar”: the minimum that qualifies as a workout for you

Maybe you don’t crush the goal every time, but clearing the bar will go a very long way. Make it accessible! Maybe the goal is a 30 minute run and the bar is a 15 minute walk, for example.
