Instead, start with heavier weights for low-to-moderate reps. Done early in your workouts, when fatigue hasn't yet set in, this protocol can induce muscle growth via both mechanical tension and muscle damage. Those mechanisms are far less stimulated when using lighter weights than when training for a muscle pump. However, higher reps are superior for driving fluids into the muscle, which increases metabolic stress. All three mechanisms are believed to contribute to muscle growth.
Most of your workout plan should include exercises that will stretch a minimum of two muscle groups in your body. For instance, the shoulder press will stretch your triceps and shoulders. On the other hand, squat will build your hamstrings and quads. Another important workout is bench press as it will work your chest, triceps, biceps and shoulders.
Do not, under any circumstances, skip rest days. Your body will not be able to build muscle effectively if it does not have time to heal and repair itself. Because building muscle means creating tiny tears in muscle fiber, which then heals, failing to give your body adequate time to repair and rest will mean few gains and the risk of serious injury.
Try incorporating "cyclical dieting" and "re-feeding" days. A possible form of re-feeding would be restricting calories for six days in a week and eating at maintenance on the seventh day—although you could adjust the frequency to meet your needs and re-feed once every two weeks or a couple of times per week. Re-feeding days help boost leptin levels, lower cortisol, and take you out of energy deficit, even if only for a day.
The third and final phase of the “25% Stronger” program helps you max out your strength levels by gradually decreasing the volume of your workouts while increasing the amount of weight you move. You’ll begin the last phase at the top end of the strength range (seven reps). Each week, you’ll perform fewer sets and reps - five of five, four of four and finally the last week in which you perform three sets of three - so your body is fresh for the final tests in Week 13.
Reverse crunch: Lie flat on the floor with your lower back pressed to the ground. Put your hands beside your head or extend them out flat to your sides—whatever feels most comfortable. Crossing your feet at the ankles, lift your feet off the ground to the point where your knees create a 90-degree angle. Once in this position, press your lower back on the floor as you contract your abdominal muscles. Your hips will slightly rotate, and your legs will reach toward the ceiling with each contraction. Exhale as you contract, and inhale as you return to the starting position.
