The eight-week block: structuring tennis fitness around your season

Tennis players rarely lack effort. What most players lack is structure: the same circuit, the same gym session and the same running loop, repeated until it stops producing anything. The body adapts to what it is asked to do, and then it stops adapting to the same ask.

An eight-week block is long enough to build something real and short enough to review honestly. Here is how the block is put together, and why each part exists.

Week 1 is a baseline, not a test to pass

The first week is deliberately easy. Loads stay comfortable, sets stay low and the goal is to learn every movement and record a starting point: what weight you used, how many repetitions you had left in reserve, how the movement felt.

That record is the whole reason the block can be judged later. Without a week 1 you have opinions about progress. With it you have numbers.

Weeks 2 and 3 build volume

Weeks 2 and 3 repeat the same movements with more work: another set on the primary lift, one more repetition, a slightly heavier load. Nothing new is introduced. The movements stay the same on purpose, because comparing week 3 with week 1 only means something if the exercise did not change.

Week 3 is the heaviest week of the first half. Two demanding sessions close together need to be separated by an easy day, and tennis counts as a demanding session even when it does not feel like one.

Week 4 is a deload, and it is where progress shows up

The fourth week cuts sets and keeps the movements. It feels too easy. It is supposed to. Training produces fatigue and fitness at the same time, and fitness only becomes visible once the fatigue from the build weeks has cleared. Skipping the deload is the fastest way to make weeks 2 and 3 disappear.

If you arrive at week 4 carrying fatigue, or with a competition in the calendar, the load comes down as well as the sets.

Weeks 5 and 6 are for the goal

Now the primary quality leads. A speed and agility block puts acceleration and change of direction first and maintains strength. A strength and power block puts the heavy lifts first and maintains court speed. The other qualities are maintained, not developed: maintaining is cheaper than building, and it leaves room for the quality you actually came for.

Week 7 consolidates, week 8 evaluates

Week 7 holds what has been built while letting you arrive fresher. Week 8 repeats the week 1 baseline work, so the eight weeks can be compared honestly instead of remembered generously.

Competitions rewrite the week

A match is not a training day you can push through. Around a competition:

• No conditioning on the match day, and nothing the day before it.
• Within three days, the session becomes a maintenance session at reduced volume: enough to keep the pattern switched on, not enough to leave anything in your legs.
• A competition week holds one session fewer than a normal week, and the load drops a step if the week would otherwise be heavy.

That is not a compromise on the plan. Staying fresh for the matches you actually play is the plan.

What to write down

Three things after each session, and the block stops being guesswork:

1. The load, with the unit and whether it was per hand or combined.
2. Repetitions in reserve on the last set, not on the first.
3. How hard the session felt overall.

Eight weeks of that is a better coaching input than any wearable.
