Doing cardio blasts burns body fat and saves you valuable time this summer. You want effective, fat-burning workouts and not 1-2 hour workouts with small results.
Combining your weight training and cardio workouts is a proven fat-burner and muscle builder. Its pretty simple, but a very tough way to do your workout! Remember that cardio exercise doesn't have to be aerobic.
Aerobic exercise is an activity that is done continuously for more than 2 straight minutes (like running on a treadmill). Research has proven that the heart health benefits of anaerobic exercise (short bursts like jumps or sprinting) is superior to aerobic exercise and you will burn more fat.
Between each weight training exercise set, do 30-45 seconds of jump rope, mountain climbers or squat jumps full speed (or your choice). It's just that simple and that tough! Try to do the whole 30 minute workout with little or no rest between exercises. Rest 2-3 minutes after completing the circuit and repeat the circuit 1 or 2 more times. This is an advanced workout technique and is guaranteed to give you maximum fat burn and heart health.
The weight training exercises you choose should be compound strength exercises. Burn more fat by working large muscle groups, not by working out longer!
Compound strength exercises (with weights or bodyweight) like squats, deadlift, lunges, standing bentover rows, squat-to curl-to press and bench press are great examples. Full-body core exercises like planks and side planks work well also. Spend less time posing on "mirror exercises" like bicep curls, calf raises and tricep extensions.
Cardio blast exercises activate and shape the bulkier, shapely fast-twitch muscle fibers and give you the body you want---lean and toned.
