Jessica Simpson isn’t exactly enjoying the view at the gym.

“Dear elderly man at the gym: it’s hard 4 me 2 keep composure whilst punching at chipmunk speed when ur ball sack spills out of ur wind shorts,” the Vh1 reality star, 29, (whose show, The Price of Beauty, premieres in March) Tweeted Wednesday.

But the, ahem, indecent exposure hasn’t soured her view on working out.

“Boxing has changed my life!” she wrote earlier that day. “I have so much energy and it has cured my insomnia. Although I don’t think I can get out of bed I’m SO sore.”

Simpson — who showed off her ample curves while out in Santa Monica Wednesday — took up boxing earlier this month.

“Second day in a row… Have I lost my marbles?” she Twittered on Jan. 7.
