Hi I started working out since last 2 months. This time also i'm doing cardio workouts and intensified it to moderate level. I burn 1200-1500 calories in gym and 500 at work daily. I measured all of it daily. Today I checked my resting bpm sitting or lying on my bed after workout and it's shockingly 165bpm. Why? I lost weight and 70 kgs right now and sweating a lot which is a good sign. But before joining gym, my bpm always used to be between 69-80. Why did it rise after working on weights and cardio fitness. Txs.
