Building strength is a lengthy process in the gym, so dive head first into going too heavy while you can’t handle it. If you’re a beginner wanting to test how much you can lift, you’re more likely to overdo it and, forgetting to use proper form and potentially giving yourself an injury that will take a long time to recover from. (This is a good reason why having a spotter is important for safety.) There are safer ways to test your strength — improving your form, looking up ways to test your maximum weight with a calculated rep scheme or utilising tempo— and you’ll be fitter and healthier in the long run.
Safety first; strength will come.
