can anyone suggest a good routine for working out alone without a spotter? i try to squat in a power rack in case i get stuck. i bench press a little more than my weight.(2 reps @225,wt is 210). i'm scared to go to failure cause once i got tired doing a lot of reps with only 135 on and had to dump weight.(left collars off lucky for me.) i'm6'5" and would like a strength routine mixed with cardio. i want strength with a lean look. also,i'm weaker in squat than bench.(about 5 or 6 reps with 185 tires me out.) can anyone help. thanks.
