90-Day DEXA Check-In: Leaner, Stronger, Still Shipping Code
Three months of very doable lifting plus low-intensity movement dropped my body-fat by 1.9%, added 5.7 lb of lean tissue, and didn’t require crash-diets, 5a.m. runs, or any other heroic measures.
From Baseline to Check‑In
Back in late February I booked a baseline DEXA scan so I’d have more than scale weight to judge the fat‑loss block I was about to start. After 90 days of four‑day lifting, extra walking, and a modest calorie deficit, I stepped back into the scanner last week. Here’s what changed—and exactly how I got there.
In Dad Bod Debugging I promised to circle back after a DEXA scan. This is that follow-up: the numbers, the context, and what actually moved the needle.
The DEXA Results
Metric | 25 Feb 2025 | 4 June 2025 | Change |
---|---|---|---|
Body-fat % | 19.1% | 17.2% | -1.9% |
Lean mass | 122.7 lb | 128.4 lb | +5.7 lb |
Fat mass | 28.9 lb | 26.5 lb | -2.4 lb |
Total mass | 157.3 lb | 160.7 lb | +3.4 lb |
What the Training Actually Looked Like
- Upper/Lower Two-Lift Template — 4 sessions/week, 45 min each.
- Movement between meetings — averaging ~8k steps/day. When I missed my target I added a 15–20 min treadmill incline walk (still Zone 2, nothing crazy).
- No running, HIIT, or circuits. Just steady walking + lifting.
- Recovery — 2 colds (6 lifting days lost) and one short vacation; on those weeks I dropped volume by half or more and got back on track after I felt better.
Total weekly time commitment: ~4 h lifting, ~2.5 h accumulated walking.
Nutrition in One Paragraph
Maintenance calories or very slight deficit on most days. Protein 1 g/lb. No foods were off-limits; the guard-rails were portion size and adequate protein.
Takeaways
- Body weight is only a proxy for real results. A DEXA gave the feedback loop I needed.
- Consistency beats perfection. Missing a few workouts wasn’t fatal; quitting would have been.
- Low-intensity movement adds up. Steps + gentle incline walks handled cardio without wrecking joints or recovery.
- A minimal program still works. Two compound lifts per session was enough stimulus once effort and progression were tracked.
Debugging Common Myths
Myth | Reality from this block |
---|---|
“You have to starve to see lose fat.” | Small deficit + adequate protein was enough to drop fat while gaining muscle. |
“Endless HIIT is required.” | Walking and the occasional incline treadmill session covered the aerobic base. |
“Busy schedule means no progress.” | < 6 hours/week total time investment moved all three metrics in the right direction. |
What’s Next?
I’m switching to a gentle surplus for a dedicated muscle-gain phase. To keep the engine healthy without beating up my knees I’m experimenting with:
- Rowing erg — short, easy sessions after lifting. Initial tests show this may not work for me.
- Rucking — starting light and gradually adding load/time. I started too eager and my knees complained, so I’m dialing back my pace and weight.
I’ll run another DEXA mid-August and report back.
