Lifting but loosing weight

"So my question is: can I assume my weight loss is from fat if my weights while lifting is still going heavier? "
Yes that's a safe assumption as you don't describe anything to suggest the real factors that cause muscle loss apply to you - inactivity or an excessive deficit.


" I’m fairly new at this but from what I can gather, cardio is bad for loosing muscle if you do too much "
Absolute twaddle for 99.9% of the population, using your muscles in any way is how you preserve or build muscle.
The 0.1% might be very lean, high level bodybuilders or ultra endurance athletes deliberately trying to stay very light and doing a volume of cardio at the boundary of what their body can sustain.

The sprinting versus endurance arguments come from looking at elite athletes who deliberately need a particular body to maximise their performance in their chosen sport. There's plenty of big guys running marathons but they won't be crossing the line first.

Watch a game of rugby or elite level rowers and see muscular guys (and gals) who also do a lot of cardio.....


If you don't want to lose weight then simply eat a bit more.

If you want to do sprints do sprints, if you want to do longer duration cardio for endurance then do that. It's not as complicated as you think for the average man or woman.

Not about really wanting to loose weight per say but the fat. I just need some more insight as to whether my current weight loss can be assumed to be from fat vs muscle since I am still progressively lifting heavier. I was confused as the more added sprints I am doing could be the cause behind suddenly dropping some weight.

Did you increase your calories when you increased your exercise? Remember it's your calorie balance that determines weight loss, gain or maintenance.

Getting stronger is a poitive sign that your training is effective. Strength and muscle size isn't a linear relationship but it's probably not worth concerning yourself with the fine details.
