Strength training is the classic winter intention and the classic January casualty, usually because it was bolted on without a plan for where it fits and started competing with the riding.
What it actually does for a cyclist
Resistance work builds strength and improves neuromuscular coordination and the stiffness of tendons. For cyclists, the most defensible benefits are better durability in the positions you hold for hours, more resilience in the hips, trunk and lower back, and better bone density, which cycling alone does not provide because it is non-weight-bearing.
What it is less likely to do is add watts to your threshold directly. If your limiter is aerobic, strength work will not fix that, and the hours are better spent riding. Anyone promising you a specific power gain from squats is selling something.
So strength work makes you a more durable rider who holds position better and breaks less often, which is worth doing for its own sake rather than as a route to a number.
Why winter, and why it usually fails
Winter is the right time because there is no result to protect, sessions are shorter anyway, and the weather makes the trade obvious.
It usually fails because it gets scheduled on top of an unchanged riding week, so the total load rises without anything being taken out and something breaks by February. The other reason is friction, because a session that needs equipment, or a gym, or a drive, ends the habit in a fortnight.
How WattPlan schedules it
The strength sessions are bodyweight, so there is no gym and no equipment, just squats, hinges, lunges, push-ups, bridges, side support, bird dogs, dead bugs and calf work. A session can happen in the room the turbo is in.
There are five sessions in two pairs plus a conditioning option. Foundation A and B are the gentler pair, run in two rounds with two minutes of work per movement at a target effort of about four to six out of ten, while Full-body A and B are the harder pair, three minutes per movement in two rounds at six to seven out of ten. Low-impact Conditioning runs three rounds. The A and B pairing is deliberate, because the two complement each other rather than repeating, so two sessions in a week cover different patterns.
You choose one or two sessions a week, and the scheduling rules are conservative on purpose.
- Strength is additional time on days you already ride. It never changes a cycling day, never alters your Load, and never moves your Fitness.
- It prefers a short easy ride with a rest or easy day after it.
- It avoids long-ride days, and the day before a demanding or long ride.
- Taper and race weeks are left free entirely.
- A recovery week gets at most one Foundation session.
The intent is that adding strength never quietly costs you a good riding session. If the week has nowhere sensible to put it, the week gets no strength session rather than a compromised ride.
How to actually stick with it
Two sessions a week is plenty, and one is genuinely worth doing, because consistency over five months beats intensity over three weeks.
Put it immediately after a ride while you are already changed and warm. Give it its own slot in the day and you will skip it.
Start at the easier end. Starting with the harder pair, being sore for four days and missing two rides is the most common way this ends in week two.
Slow the lowering phase rather than adding repetitions when a movement gets easy, because bodyweight work stays demanding for a long time if you control the descent.
When to stop
Reduce it as your riding load rises in spring, and drop it entirely in a taper, because strength work in race week adds fatigue and no fitness you can use. WattPlan's scheduler already leaves those weeks alone, but if you are doing this on your own, that is the rule to copy.
