Stop and get medical help
If you get chest pain or pressure, feel faint or dizzy, are unusually breathless, or your heart races or beats irregularly during exercise, as our plans advise. The American Heart Association says these need immediate medical evaluation.

Call 999 (911 in the US)
For chest pain that comes on suddenly and doesn't go away, feels tight or like squeezing, or spreads to your arms, neck, jaw, stomach or back; a sudden, extremely painful headache, for example during a heavy press (the NHS says a bleed on the brain may be more likely when lifting something heavy); someone who faints while exercising; palpitations that don't go away, or come with chest pain, breathlessness or feeling faint; or signs of a stroke, even if they've stopped. Don't drive yourself to A&E.

Check before you start
If you haven't exercised for some time or have a medical condition, speak to your GP first, as the NHS advises. Get advice before heavy lifting if your blood pressure is uncontrolled, or you have heart disease or chest pain when you're active, a pacemaker or defibrillator, diabetic eye disease, glaucoma, a hernia, recent eye or tummy surgery, or you're pregnant, as our breathing guide lists.

A shoulder out of place
Call 999 or go to A&E if, after a fall or injury, or after your shoulder slipped during a press, your shoulder looks out of place or has changed shape, or you can't move your arm. Don't drive yourself, and don't try to put it back in.

A sudden shoulder problem, or a pop
Ask for an urgent GP appointment or get help from NHS 111 for sudden or very bad shoulder pain, an arm you can't move, a badly swollen or misshapen shoulder, pins and needles that don't go away, or pain after an injury. A sudden pop or snap with pain at the shoulder or upper arm needs a GP or NHS 111 the same day; a pop or tearing at the front of the armpit or chest, then bruising or a change of shape, needs NHS 111 or an urgent treatment centre the same day.

Shoulder pain that doesn't settle
See a GP or physiotherapist if pain is getting worse or hasn't improved after 2 weeks of looking after it yourself, or it's very hard to move your arm, or if your shoulder has partly or fully come out of joint, or you worry it might.

Your back
Call 999 or go to A&E for loss of feeling or numbness around your genitals or bottom, new trouble peeing or controlling your bladder or bowels, changes in genital sensation during sex or problems with erections or orgasm, or pain, tingling, weakness or numbness in both legs: signs of cauda equina syndrome. Don't drive yourself.

Your wrists
Contact NHS 111 if you have severe wrist pain, feel faint or sick from the pain, heard a snap, grinding or popping noise, can't move your wrist or hold things, or it has changed shape or colour. See a GP if the pain hasn't improved after 2 weeks of treating it at home, is getting worse or keeps coming back, or you have tingling or loss of feeling.

If a bar or plate lands on you
Call 999 or go to A&E if you heard a crack, or the injured part has changed shape, points at an odd angle, is numb or tingling, or has turned blue or grey or cold. If a rep stalls in front of your head, push the bar forward and step back rather than fight it, as the move page says.

A new lump or bulge
See a GP if you think you have a hernia, and get help from NHS 111 if a hernia becomes painful or you feel sick. Call 999 or go to A&E for a femoral hernia (a lump at the top of the thigh) with very bad tummy pain, sickness, being unable to fart or poo, a high temperature or sudden confusion.
