is training solo about useless? iv trained always with a partner to push me but i have been training alone just with an ipod and i didnt have to wait on anyone but myself got my rest periods perfect and got in and got out in little over an hour....u dont need that spotter to grow the most effectively do u ??? i did rest pause on smith with close grip bench drop sets and single arm dumbbell forced reps think ill get the same results without a spot?
