Structured Power Training Weekly Plan: Wednesday Workout with PTZ3 Sweet Spot Training

Introduction

“Structured training” is still a relatively unfamiliar concept to many cycling enthusiasts in Taiwan. Most people ride based on feel: ride faster when in a good mood, take it easy when the weather is bad. However, the proliferation of power meters has brought training into another dimension—scientific training with goals, intensity, and periodization. This article centers on Sweet Spot training (PTZ3, 88–93% FTP) and designs an executable weekly plan for office workers who only have three days per week to train.

What is Sweet Spot Training?

The Sweet Spot sits at the upper edge of Zone W3 to the lower edge of W4, approximately 88–93% of FTP. What makes this intensity special:

• Sufficient training stimulus: It significantly boosts FTP, far more efficient than pure W2 aerobic training
• Relatively manageable fatigue: Easier to recover from than all-out threshold training (W4), allowing for higher training frequency
• Maximum time efficiency: Within limited training time, it maximizes stimulation of both the aerobic and mixed aerobic-anaerobic systems

Research shows that accumulating 2–3 hours of effective training time in the Sweet Spot zone per week is an efficient path to improving FTP for amateur riders.

Wednesday Workout Design Principles

Based on three training sessions per week, here are the intensity allocation principles:

Detailed Workout Content

Tuesday: Sweet Spot Main Day

Goal: Improve aerobic threshold, increase mixed aerobic-anaerobic system efficiency

1. 15-minute warm-up (W1–W2, easy spinning)
2. Main sets:
   • 2×20 minutes Sweet Spot (90% FTP), 5-minute rest between sets
   • Or 3×15 minutes Sweet Spot, 4-minute rest between sets (beginner version)
3. 10-minute cool-down

Indoor recommendation: Use Zwift’s Sweet Spot workout or TrainerRoad’s Antelope workout, letting the trainer control power for greater precision.

Thursday: Threshold Climbing Day

Goal: Improve lactate clearance ability, strengthen climbing endurance

1. 15-minute warm-up
2. Main sets:
   • 2×10 minutes threshold (100% FTP), 5-minute rest between sets
   • Recommendation for Taiwan riders: find a fixed 10-minute climb (such as Muzha Maokong, Pingxi Lingjiao, or the Shiding Huangdi Temple area)
3. 10-minute cool-down

Saturday (or Sunday): Long Aerobic Day

Goal: Build aerobic base, improve fat metabolism efficiency

1. Maintain W2 zone throughout (56–75% FTP)
2. Suggested routes: in northern Taiwan, ride the Beiyi Highway out-and-back; in southern Taiwan, ride along Provincial Highway 1 or the Gaoping River
3. Nutrition strategy: replenish 50–70g of carbohydrates per hour to sustain steady long-duration output

Training Load Management

The biggest risk of Sweet Spot training is overtraining—because the intensity “isn’t that high,” people mistakenly think they can ride every day. The correct approach:

• Use a three-week training microcycle: Weeks 1–2 follow the normal plan; week 3 reduces volume (training volume decreased by 30–40%, intensity unchanged)
• Monitor HRV (heart rate variability): If morning HRV drops significantly, switch to a W1 recovery ride or complete rest that day
• Sleep is the best recovery tool: Ensure 7–8 hours per night, especially after high-intensity sessions

Practical Advice

1. Start with the lower-intensity version: When first trying Sweet Spot training, begin with 3×15 minutes at 85% FTP, then increase once adapted
2. Maintain a steady pace: The most common cause of failed Sweet Spot sessions is uneven pacing; use ERG mode to let the trainer automatically maintain power
3. Record how each session feels: RPE should be between 6–7 after completion; if you feel completely exhausted every time, your intensity is set too high
4. Pair with foam rolling and stretching: Especially relaxing the quadriceps and glutes after training to reduce residual fatigue before the next session

Conclusion

Sweet Spot training is the most worthwhile training strategy for time-constrained office-worker riders. With three sessions per week totaling 4–5 hours, if you can accurately hit the 88–93% FTP Sweet Spot, a 5–15% FTP improvement over 8–12 weeks is a completely achievable goal. Combined with Taiwan’s abundant mountain road resources, applying structured trainer workouts to outdoor climbs—giving every ride a clear purpose—is the essence of smart training.
