HIIT vs LISS cardio on GLP-1 — looking for input

I trained through the whole thing, three times a week, and the effect on the scale was almost nothing while the effect on everything else was large.

Exercise-induced nausea amplification with training: I learned the hard way that intense exercise within 24 hours of injection can make nausea much worse. The combination of delayed gastric emptying + exercise-induced blood flow redistribution is rough on the GI system.

My workaround: inject Friday evening, do low-intensity activity Saturday, and save my intense workouts for Tuesday-Thursday when the GI effects have subsided. Timing your training around your injection schedule is a real optimization strategy.

Exercise transformation with training: went from barely able to walk a block to completing a 5K last month.

My fitness journey alongside GLP-1 therapy:

• Month 1-2: Walking 15 min/day
• Month 3-4: Walking 30-45 min, started bodyweight exercises
• Month 5-6: Joined a gym, started resistance training
• Month 7+: Running, lifting heavy, yoga for fun

The weight loss made movement possible. The movement made more weight loss possible. Virtuous cycle in action.

Same experience, arrived at from the opposite direction. The detail I would add is minor and it is already implied above.

From the other side of the consultation, briefly.

Gym confidence after training weight loss: walked into a gym for the first time in 10 years yesterday. Was terrified. But you know what? Nobody stared. Nobody judged. Everyone was focused on their own workout.

Started with 20 minutes on the treadmill and some machine-based resistance exercises. Nothing fancy. But I DID IT. And I'll go back tomorrow.

To anyone too intimidated to start: the hardest rep is walking through the door. Everything after that is just movement. 💪
