Sugar is often added to processed foods and beverages. The U.S. Food and Drug Administration’s updated nutrition labeling requirements will include the amount of added sugars, and until the rollout is complete, a study published in The American Journal of Clinical Nutrition offers insight into the added sugar content of beverages.
Researchers analyzed 160,713 beverages purchased by U.S. households from 2007 to 2012. Although the amount of added sugar in beverages did not change significantly over time, the sugar’s contribution to beverage calories did increase. The average 12 grams a day of added sugars accounted for 32% to 48% of the calories in packaged beverages.

To get in more days of training and allow adequate time for recovery, weight lifters often split their workouts between upper and lower body muscle groups. You can also split training sessions between pushing and pulling movements. A study published in the International Journal of Sports Physiology and Performance compared the force production characteristics of three pulling compound movements.
Researchers had 16 men with weight room experience stand on a force plate while doing reps of the hang power clean, jump shrug and hang high pull. They found that jump shrugs produced the highest relative peak force and greatest rate of force development. Jump shrugs also produce different force-time characteristics during the final stage of the movement.
General Fitness

Being able to generate greater force from lower body muscle groups can be a competitive advantage in a number of short duration track and field events. A study published in the Journal of Strength and Conditioning Research offers a simple tip for boosting force production.  
Subjects were evaluated before and after a warm up consisting of plyometric drop jumps or low-paced walking. Drop jumps increased the rate of force development by an average of 39%, with the effect lasting for around 6 minutes. The walking warm up actually decreased rate of force development.
