Don't handle more weights

Allot a day of workout to a certain muscle group. Take this schedule for
example: Day 1 – chest, shoulders and triceps; Day 2 – quads, calves and abs;
Day 3 – back, biceps and forearms. This enables you to give enough attention
to each body part for maximum stimulation.

Do not abuse your body by subjecting it to more weights than it can handle.
You should feel your muscle resist the weight but not too much that you
couldn’t perform your routine properly. You should be able to lift the weights
in the right manner from start to finish.

As a beginner, it is easy to overlook signs of overtraining due to eagerness.
Overtraining must be avoided at all costs since it negatively affects
testosterone levels and leads to lower immunity to sickness. Signs to watch
out for: weak appetite, heightened blood pressure, drastic weight loss,
irritability and higher heart rate even at rest.
