Get lean and strong like a MMA fighter without wasting time in the gym. Look, feel and perform like an ancient spartan warrior – How to become an absolute physical beast. It’s time to start imagining yourself as one of the mighty 300, a Spartan soldier trying to fend off a overwhelming army in order to protect your people and your way of life. In this bodyweight training program you’ll learn how to fire up your metabolism to burn body fat, build muscle strength and endurance and reveal your true Spartan Warrior body. Our workout challenges and exercises have been selected for their functional value. Bodyweight movements have been selected to build explosive agility, as well as to challenge the grip and stamina. We created a challenging body transformation plan that promises results in 30 days based on bodyweight training exercises. This 30-day plan based on Spartan Warrior training will help moderately-fit people get stronger and reveal more muscle definition with four workouts a week. If you’re super overweight, you’ll still be able to lose weight and build muscle strength, but you might not be six-pack ripped in 30 days if you have a lot of weight to lose. If you’re looking for an honest, kick-ass workout that will test your physical boundaries and transform your body, you’ll get results by sticking to the Spartan Warrior Fighter workout for at least 30 days.
