HIIT WORKOUT TO TARGET ARMS

HIIT is a training idea in which low to moderate intensity intervals are alternated with high intensity intervals.
HIIT can be applied to running or to exercises such as squatting. HIIT is considered to be much more effective than normal cardio because the intensity is higher and you are able to increase both your aerobic and anaerobic endurance while burning more fat than ever before.
Anaerobic literally means "Without oxygen." The anaerobic energy system is what provides energy in all out efforts of up to 1 minute. For the first 10-15 seconds, the phosphate pool is used up and after that, glycolysis and lactic acid are involved in the effort.
During 10-15 second bursts, there is a very small amount of lactic acid produced. Rest periods of 30 seconds to a minute will provide complete recovery of the Adenosine Triphosphate-Creatine Phosphate (ATP-CP) system. During efforts of more than 10-15 seconds, a large amount of lactic acid is produced and such efforts are extremely taxing on both the athlete's muscles and their Central Nervous System (CNS).
This quick arm workout will make your upper body burn and your heart rate soar.
Turning your arm workout into a high-intensity interval session makes the most of your time in the gym, both with a shorter bout overall (just 15 minutes!) and by adding even more value to those single-joint moves like curls and tricep extensions.
The moves in this workout are designed to maximize fat burn while targeting specific muscle groups in the upper body for optimum results.
Choose dumbbells that you can safely move with good form for the full minute of each strength move.
