Are Major League Baseball players doing more harm than good by embracing year-round conditioning programs?

Is there too much emphasis on weights and body-building exercises within pro sports today, especially baseball?

The numbers in an AP report from early this morning are alarming. Especially for the start of another big league season, when players are supposed to be in tip-top shape.

The article states that a record 115 MLB players are on the disabled list to start the season. There were 101 players on the DL to open the 2014 season, 110 in 2008 and 104 in 2001, AP reported, citing data from MLB’s commissioner’s office. In 1995, when the commissioner’s office began keeping these records, 46 players were on the DL on Opening Day.

Do these players have enough muscle flexibility? Are they doing the wrong exercises to prevent injuries?
