Eight weeks of gym-based strength for endurance athletes

This Intermediate strength plan is for cyclists, triathletes, runners, and other endurance athletes who want a focused strength base before moving into a build or maintenance phase. It is a strength plan—not a complete cycling, running, or triathlon schedule.

Best fit

• You already train consistently and can perform basic loaded movement patterns with sound technique.


• You have access to a full gym, including barbells or dumbbells, cables, and machines.


• You want a repeatable eight-week routine that develops strength alongside your endurance training.

Plan structure

• Three programmed gym-strength sessions each week: a heavier strength-and-power day, a stability-and-endurance day, and an explosive-and-functional day.


• Seven 20-minute deliberate walks each week to support consistent low-intensity movement.


• Repeated exercise patterns that let you improve technique while progressing load and effort.

Time commitment

TrainingPeaks displays 2 hours 20 minutes per week from the seven scheduled walks. The three rep-based strength sessions do not carry fixed durations, so allow additional time for warm-up, working sets, and appropriate rest.

How to execute the work

Choose loads that allow controlled technique across the prescribed work. Where the workout presents two rep targets, treat them as a working range and select a load that matches the intent without sacrificing form.

What you need

• Access to a full gym.


• Confidence with basic strength exercises, or in-person instruction when needed.


• An existing endurance schedule managed separately.

Use this plan when your sport training leaves room for three weekly strength sessions and your goal is to establish a durable gym-strength base.
