In order to lose fat from one specific region, you need to burn more calories than you consume. This can be achieved by cutting your daily caloric intake down to 500 calories. Apart from this, you have to burn calories through exercise. It is advisable not to drastically cut down your caloric intake as this may deprive your body of energy and cause fatigue and dizziness. Hence, you should gradually cut your caloric consumption and burn more calories than usual.
Exercise acts as a temporary diversion to daily stresses and it improves self-esteem. Increased core temperature during exercise may lead to reduced muscle tension and favourable alterations in brain neurotransmitters. Mood improvements may also occur due to the increased secretion of endogenous (internal) opiates, e.g. endorphins. Psychological changes may occur because of changes in norepinephrine, dopamine and serotonin, all hormones which can affect mood and anxiety levels.
Back to the tricep pushups and really activating those tricep muscles for toned arms. If you need a rest, that's totally cool. Just take a break in the up position and maintain that plank form.

For those who are more advanced, we want you going as hard as you can and trying to hit that 15 to 20 reps. You're doing great.
