Specific suggestions: 1. Only for those who have no training foundation, personal experience, although strength training, can't be trained for a long time at first, because your physical strength is limited, so if you do strength training every day, novices can keep it at 15-20 minutes, which is almost enough. 2. Tools can be dumbbells or resistance bands. Personally, I think the dumbbell effect will be better. Simple and rude tools and online tutorials are also easy to find. The resistance belt is suitable for travel and does not take up much space, but there may be less online tutorials. 3. Strength training suggestion combined with aerobic fitness training, many aerobic exercises are good training for the whole body. It is not easy to do aerobic exercise with proper intensity seriously, and it can be done in about 30 minutes. There are many tutorials online, using yoga mats, similar to Pilates. Aerobic training can better improve the overall physical fitness of the body.
