I don't science in the anti-science threads, but if anyone is interested in the science of "Should I lift weights if I had a MI or am at high risk":

Based on studies reviewed in this paper, recommendations can be made for the weightlifting training of patients with coronary artery disease.

Since the mid-1980s resistance training has become an accepted part of the exercise rehabilitation process for patients eligible for traditional cardiac rehabilitation programs.

Resistance training has beneficial effects on particular cardiovascular risk factors in postmenopausal women.

The guidelines for cardiac rehabilitation clearly state that the long-standing perception that resistance exercise is harmful to cardiac patients is not supported by the scientific literature

Resistance training (RT) is a core component of cardiac rehabilitation. We investigated the effects of RT on exercise capacity, muscle strength, and mobility in middle-aged and elderly patients with coronary artery disease
Resistance training could increase exercise capacity and muscle strength in middle-aged and elderly patients, and mobility in elderly patients, with CAD

Muscular strength is inversely and independently associated with death from all causes and cancer in men, even after adjusting for cardiorespiratory fitness and other potential confounders.

In general, regular exercise has proven to be extraordinarily safe and the theoretical and proven benefits appear to greatly outweigh the risks for most people, including those with CHD, those with severe left ventricular dysfunction, and the elderly.

In summary, resistive training appears to be safe and effective for developing fitness and improving risk factors. Contemporary exercise training guidelines have endorsed resistive training as part of the exercise prescription for most healthy adults as well as many patients with coronary heart disease.

Note: These are not in order temporally. Additionally I was unable to find anything about "really big jacked dudes who had MI", so the specific application to G4S may be fuzzy. However, for the vast majority of us, lifting heavy things will probably enable us to have a not-so-****ty quality of life and will be recommended if we do have a heart attack. (And prob recommended to start even if we wanna avoid one.)
Note2: Obviously there is no scientific or medical stance on anything since like... Climate change, gravity, magic sky man, etc etc.
