This might be impossible to answer, but i was wondering if u are trying to gain strength and loose fat if it is better to run and work out or just work out. So if i dropped my calorie intake from 2500 to 2100 while on a diet should i run still or not to try and gain strength or should i just leave it at 2500 and just run and burn 400 cal.? I know u really shouldent run or not run for more than 30 min. and keep your bpm below 140 when trying to gain strenth, but would running to loose weight be better than cutting calories to loose weight or both?
