The last time i was in the gym, jog
ged about 15 minutes, felt i didnt push myself to bad,rested for
a little bit, went over to the chest press machine and did an 8 rep set ( weight i could do without to much strain) I stopped exercising for
the day.. after that 8 reps i couldnt get my heart rate
probably 30-45 minutes. it probably was about 118-150 when i was done with the 8 reps i felt like i coudnt recover like i was still running.
