Your job is turning physiology into spreadsheets: periodized plans, velocity targets, fueling numbers. These tools are the spreadsheet-free version — Bompa macrocycles generated from a competition date, bar speed converted to daily max, VO2max from a stopwatch.
Yes — the linear macrocycle structure from Periodization: Theory and Methodology: anatomical adaptation, maximum strength, conversion to power or sport-specific strength, taper. Loads and rep ranges follow his published tables; the planner scales phases to your calendar and lengthens adaptation for novice athletes.
Pick one main lift per session, record mean velocity on working sets for two weeks to build each athlete's profile, then use the VBT calculator's reference table as the shared language: "today we work at 0.55–0.65 m/s" lands better than "85%" on a fatigued Tuesday.
That is the design — no logins, works on the weight-room tablet or a phone. Many S&C staffs embed calculators on their team portal using the free embed snippet at the bottom of each tool page.
