I use a single printed sheet for each week. I carry last week plus this week. That helps me to update the current sheet based on last week. Then each week, I throw away the old sheet. It's enough for me. As long as I am progressing week over week, that is enough. Are you aware of meso-cycles? Basically: 4-8 weeks on, then one week at half weight, half reps, or full rest. You can really build a lot more muscle using meso-cycles.
