# I Cut My Workouts In Half (The Results)

> Source: [I Cut My Workouts In Half (The Results)](https://youtube.com/watch?v=Oj5lC-06ags)

## Summary

The video documents a 100-day self-experiment where the creator reduced their workout volume from three to four sets per exercise to just one or two, aiming to determine whether muscle mass and strength would be lost, maintained, or gained. Using DEXA scans and strength tests, the creator tracked changes in body composition and performance, ultimately finding that despite halving training volume, strength increased and fat loss continued.

### Key Points

- **Experiment Setup** [00:01] — The creator halved their usual workout volume, doing only one or two sets instead of three to four, for 100 days.
- **Measurement Methods** [00:14] — DEXA scans and strength tests were used to track changes in muscle mass and strength throughout the experiment.
- **Strength Results** [00:27] — Despite half the volume, strength increased: new PRs on pendulum squat and chest press, bench press stayed the same, and leg extension increased by 15 lbs.
- **Body Composition Results** [00:40] — During a cutting phase, DEXA showed a loss of 5.5 lbs of fat mass and 1.8 lbs of lean mass.
- **Overall Verdict** [00:56] — From day 30 to day 100, lean mass loss was within margin of error; based on physique and strength trends, halving workouts was deemed a massive success.

### Conclusion

The experiment suggests that significantly reducing training volume can still yield strength gains and effective fat loss, challenging the assumption that high volume is necessary for progress.

## Transcript

only did half your workout? And you did that for 100 days. Would you lose muscle, maintain it, or keep gaining? Well, that's exactly what I did for the last 100 days. Instead of my usual three to four sets, I only did one or two. And
to see if I'd lose muscle, I got DEXA scans done, and I tested my strength. At enough. Our workouts now only took 45 minutes. But by the halfway point, my recovery was better than ever, and I was loving training. And after 100 days,
despite doing half my usual volume, my strength actually went up. I set new strength PRs on the pendulum squat and the chest press machine in the final week, and my bench press stayed the same. But my leg extension went up 15
lbs. As for my physique, I was cutting, so my DEXA showed that I lost 5.5 lbs of fat mass and 1.8 lbs of lean mass. But from day 30 to day 100, I actually probably within the margin of error, but based on my physique and my overall
strength trends, I'd say cutting my workouts in half was a massive success.
