Here are 3 exercises that people need to do more often to help with your muscle gains.
1) INCLINE DUMBBELL BENCH PRESS- Ok, so I know a ton of people bench and work their pecs, but not many people do incline often and with enough volume. Dumbbells are great because they allow for a greater range of motion more so than the traditional barbell does. Also, incline press will help your anterior delt ( front of the shoulder ) and upper pec to develop at greater speeds which will result in a fuller looking chest. Every 3 weeks or so try to change the angle of the incline slightly to keep yourself progressing in the workouts.
2) STIFF LEG DEADLIFT WITH BARBELL-Nothing beats these in terms of really torching your hamstrings. Focus on a controlled lowering of the bar to get that negative and then explode on the way up. Mix up your rep schemes by going heavier with low reps ( 3-5 ) on some weeks and then going moderate weight with medium reps ( 8-10 ) on others. Make sure you always keep great form and never spare the back by trying to do too much weight1
3) WALL BARBELL BICEP CURLS-I love these things because they help you avoid cheating. Normally you do a standing bicep curl and by the end your rocking, your back and shoulders are working and it becomes a mess. Now that you wont cheat as much you can get greater recruitment of the bicep than before. Get yourself against a wall and keep your butt, and whole back against it the whole lift. I stand with my feet about 1-2 feet away from the wall.
