Presumably the intention is you use the time while the weights are easy to work on form, injury rehab etc with the hope that when you get back to proper weight you’re able to push on quickly?
That’s the plan. My knee may disagree though! Form is vital - follow the vids or look for Mark Rippetoe for the best guidance.
The weights get heavy quite quickly if you have time to devote to it.
