fponewsletter_teaser: Pilates exercise and resistance training both increase deep muscle thickness of the internal obliques in female exercisers. Which is more effective for conditioning the transversus abdominis, according a study involving both experienced and novice exercisers?
Rest is often a carefully thought-out variable in strength training routines. Rightly so, suggests research published

to suggest biofeedback training. Sport psychology researchers from the University of Ljubljana in Ljubljana, Slovenia, conducted a study to evaluate whether 8 weeks of
biofeedback training could improve control over competitive anxiety and enhance athletic performance among top-ranked athletes. All subjects took biofeedback stress tests both before and after the 8-week period.
