India, May 11 -- Actor, presenter, and fitness enthusiast Mandira Bedi, at 54, is proving time and again that fitness is a lifestyle, rather than a momentary task. On Friday, she took to Instagram to share her 'go-to' shoulder workout, showing off the incredibly toned arms and sculpted delts that have become her trademark. With a playful mix of intensity and humour, Mandira Bedi shared a peek into her weight training regime, and it's filled with power and a little 'torture' too. Mandira follows a time-under-tension approach, which is a proven method for building lean muscle and improving muscular endurance. She wrote in her caption, "My go-to shoulder moves! 3 sets 40 seconds each move (with a little of the weighted hula hoop thrown in, because.. why not!!) The last exercise: snow angels are absolute torture!!" Mandira's routine included a mix of classic strength moves and creative additions like dumbbell overhead presses, a staple for building shoulder strength and stability. She also performed lateral and front raises, which are targeted movements to sculpt the front and sides of the shoulders, and kettlebell upright rows, which focus on the traps and upper back for that defined look. Mandira stressed this specific exercise as particularly challenging. Performed with light weights through a full range of motion, snow angels are an absolute burner for the rear delts and rotator cuffs. She then threw in some weighted hula-hooping between her sets, which is an absolutely fantastic core workout and keeps the heart rate elevated....
