This is a 4-day split strength training plan designed for both intermediate and advanced level gym goers. More experienced weight lifters simply use a higher percentage of 1-RM for major lifts like squat and bench press. The program is take from a 2013 research paper published in the Journal of Strength & Conditioning by Mike Greenwood et al. The exact order of each exercise - in each training session - was followed as reported in the study. Subjects performed 3 sets of each exercises, resting 90-seconds between sets. Nutrition One of the many interesting thing I found in the study was on the nutrition side. Protein intake was significantly increased from baseline of the study. The male subjects in the study consumed 22-29 percent of their total calories from protein which equated to about 190-200 grams/protein each day for 12 weeks while on the study. This included 20-grams in the form of a post workout drink. Program Design Day 1 - Training Focus: Upper Body Push. Includes 8 exercises x 3 sets each - 60-75 minute workout time.
