Free weights and machines engage your muscles in different ways, although both contribute to building strength and stability.
Free weights like dumbbells are great for improving coordination, and they engage stabilizer muscles, which leads to building truly functional strength. Once you start training with free weights consistently and equipment like
Pilates Power Kit consistently, you may feel an improvement in overall strength as well. On the other hand, machines can be useful for targeting specific muscle groups, but as they are fixed, they only offer a limited amount of benefits to building overall body stability.
