Asgard’s defenses were fashioned in the sinew of its guardians. This means only one thing for you now: work, baby. Work hard. 

Instructions: Repeat each move with no rest in between until the set is done, rest up to 2 minutes and repeat the whole set again 3, 5 or 7 times depending on your fitness level.

What it works: full body; workout with the main accent on strength and muscle building. Quads, triceps, biceps, chest, abs

Tips: Breath sharply out when performing sitting twists. This helps flatten your stomach, tense your lower abs and give you faster results.
