Quantify Your Training
Training Stress Score (TSS) and training load metrics help you balance fitness gains with recovery. Train hard, recover smart.
Training load metrics like TSS help quantify the stress of your workouts. By tracking cumulative load, you can optimize training stimulus while avoiding overtraining.
Understanding TSS
Training Stress Score (TSS) combines duration and intensity into a single number. A workout at threshold for one hour equals 100 TSS. Higher intensity or longer duration means higher TSS.
Acute vs Chronic Training Load
Acute Training Load (ATL) is your recent fatigue. Chronic Training Load (CTL) is your fitness. The difference (TSB) is your 'form' - how fresh or fatigued you are.
Managing Training Load
Build CTL gradually (3-7 TSS/week). Monitor TSB to time peak form for events. Allow recovery weeks every 3-4 weeks of hard training.

Frequently Asked Questions
What's a good weekly TSS target?
Weekly TSS depends on your fitness and goals. Recreational athletes might target 300-400 TSS/week, while serious competitors might reach 600-900+. Build gradually.
Does TSS work for running?
Yes, Rivo calculates TSS equivalents for running using pace and heart rate. The concept of training stress applies across all endurance sports.
