Exercise is that magic little pill everyone is looking for — you know, the one that makes you lose weight, boosts your mood and generally improves your life. Weightlifting, in particular, can foster scores of benefits, both physical and emotional.
Despite the vox populi that lifting weights makes you “bulk up” (it doesn’t, ladies), it can actually help you lose weight and slim down. Beyond the purely physical, lifting weights can improve your bone health and increase your metabolism, just to name a couple of benefits.
For those curious about weightlifting but boggled with questions, I rounded up some of the most common questions about lifting weights that I hear as a personal trainer and CrossFit coach. By the end of this guide, I hope you’re ready to pick up some dumbbells (or a couple of wine bottles) and start building muscle.

High-speed photography shows a sneeze can blast saliva and mucus well beyond current social distancing guidelines, and tiny droplets can remain in the air longer than thought.
For anyone who grows anxious at the sound of a sneeze or a cough these days, Lydia Bourouiba’s research offers little comfort.
Bourouiba, a fluid dynamics scientist at MIT, has spent the last few years using high-speed cameras and light to reveal how expulsions from the human body can spread pathogens, such as the novel coronavirus. Slowed to 2,000 frames per second, video and images from her lab show that a fine mist of mucus and saliva can burst from a person’s mouth at nearly a hundred miles an hour and travel as far as 27 feet. When the sternutation is over, a turbulent cloud of droplet-containing gas can remain suspended for several minutes, depending on the size of the droplet.

The deadly coronavirus bug could be spreading across the globe through farts, according to doctors.
Tests carried out earlier this year have shown that the virus was present in the feces of more than half of patients with COVID-19.
And doctors have previously warned farts to contain tiny poo particles that can spread bacteria.
They said more research needed to be done to rule out passing the disease on to people through omitting bodily gasses.
TV doctor Xander Van Tulleken, who presented the CBBC series Operation Ouch as well as appearing on a string of documentaries, raised the issue on social media.
