I have been working out for about 3 weeks now.

My workouts are normally structured like this:

30 mins on the treadmill as warmup
3 sets of 10 reps for various machines based on the target muscle, with increasing weightage of 10kg each rep
- usually divide muscle areas as chest, abs, limbs, back spread across all week
10 mins on the treadmill as cooldown

i do this at least 4 times a week. this is the most hardworking i have been all my life, but i think i am not getting enough rest.

yesterday i went for the legs, doing leg presses, curls and extensions.

usually the day after i will feel super sore, but nowadays i don't feel sore anymore.

is it that my body is now used to working out, or should I increase the difficulty of my training?

this happens when i started to eat at least 2 boiled eggs every morning.

I've read a lot about this. I started out with soreness all over my body to the level that I can't walk properly. But now, I don't feel as much soreness.

A lot of people suggests that soreness =/= good workout...

I usually treat it as a sign that I'm stronger ..

I thought of this point too, so I purposely increased the weight/resistance in the machines that I used yesterday.

No soreness today. It felt like I did not work out at all yesterday.

Did I just hit the plateau or something? Or maybe I should vary my workout a bit, like swimming instead of brisk walking, use the free weights instead of machines.

Did some search around the net and found some articles:

Apparently no soreness doesn't mean you are not building muscle. It means the body is getting used to the workout. I need to push myself with new routines!

Yeah, but I thought adding weight = challenging your body as well ?

Not heavy enough it seems... must make sure I maintain the correct form each lift. Will try again tomorrow.

Today is rest day!

You are correct TS, DOMS @ Muscle Soreness isn't an indicator for a good workout. If you don't feel the DOMS, then it's good. You don't want be limping around the next day after doing leg day each week no?

Just asking, do you have a proper workout routine?

No I don't, and I intend to get one (like right now, reading the stickies).

Go get one in BB.com la

Haha, bookmarked already. There is so much to read!
