Hey,

So I've been doing Dumbbell workout to gain muscles and lose weight.

But I noticed my muscles stop growing (Over-train) even though I can carry heavier weight (From 10 to 12.5kg now).

So after reading from some site it says I need rest, the question is;
- For how long?
- Do I need to rest if I do dumbbell workout for weight loss?
- If I stop doing dumbbell workout for 1-2 days, is it okay if I do some jogging activities during that 1-2 days?

Hey,

So currently, I do 3 type of barbell exercises.
-Bicep Curl
-Behind Shoulder Press
-Front Shoulder Press

I usually does it at 20kg, and lately I increase the weight to 30kg and was able to do both shoulder press at 15 reps x 3.

Im planning to increase 10 more kg, so is it okay doing bicep curl at 40kg? Anything that I need to watch for to prevent hand injury or such?
