If You Only Have 20 Minutes in the Gym
If you only have twenty minutes in the gym, there is one thing to do – resistance training. Forget cardio or classes, just do your resistance training. Resistance training will help you burn more fat, induce EPOC (boost in metabolism after workout), and increase strength. In fact, if you only have 30 minutes three times a week, resistance training is the best training for you. Just make sure your training is balanced so that if you do a push like a bench press, do a pull like a seated row. Also, if you do a back exercise like back extensions, do a core exercise like single-leg extended sit-ups.
