Advanced45 minRowErg
Six 1,000-metre repeats at threshold intensity with three minutes of rest. This workout targets the lactate threshold zone, improving your body's ability to clear lactate at high work rates. An essential session for anyone aiming to improve their 2K or 5K time.
Warm-Up
| Interval | Target Split | Rest | Notes |
|---|---|---|---|
| 5 min | 2:15-2:25 | - | Easy rowing at 18-20 spm |
| 3 min | 2:05-2:15 | - | Moderate pressure build |
| 4 x 10 strokes | Target pace | 30s easy | Prime the legs |
Main Set
| Interval | Target Split | Rest | Notes |
|---|---|---|---|
| 1000m | 1:48-1:55 | 3:00 | Rep 1: ease into the target split |
| 1000m | 1:48-1:55 | 3:00 | Rep 2: match rep 1 exactly |
| 1000m | 1:48-1:55 | 3:00 | Rep 3: halfway, check your form |
| 1000m | 1:48-1:55 | 3:00 | Rep 4: mental battle begins here |
| 1000m | 1:48-1:55 | 3:00 | Rep 5: hold the standard |
| 1000m | 1:48-1:55 | - | Rep 6: give everything, negative split if possible |
Cool-Down
| Interval | Target Split | Rest | Notes |
|---|---|---|---|
| 3 min | 2:25+ | - | Easy rowing |
| 2 min | Very easy | - | Gentle cool-down to normalise heart rate |
Coaching Notes
- +Threshold pace is roughly your 5K race pace or 8-10 seconds above your 2K split.
- +Heart rate should reach 85-90% of max by the end of each rep.
- +Active rest is critical — row lightly during the 3-minute break rather than stopping.
- +If you cannot hold pace on rep 4, the target was too aggressive.
- +This session produces significant training stimulus — allow 48 hours recovery before the next hard session.
Frequently Asked Questions
What is threshold training?
Threshold training targets the intensity at which lactate begins to accumulate faster than it can be cleared. Training at this intensity improves your lactate clearance rate, allowing you to sustain harder efforts for longer.
How should the 3-minute rest feel?
You should feel partially recovered but not fully fresh. Heart rate should drop to 120-140 bpm before the next rep. If you feel completely recovered, the work intensity is too low.
Can I do 5x1000m instead of 6?
Absolutely. Start with 4-5 reps and build to 6 over several weeks. Quality of each rep matters more than total volume.
